If life is a journey, it's no weekend jaunt to the beach. It's an around-the-world expedition riddled with dangerous passages and course corrections.

My marriage is a journey, unfortunately quite a rough one of late. My relationship to my ailing father and my siblings who also help take care of him is always under construction.

Like many people, I also grapple with work-life balance: how much of myself do I put into my job or even any given project, and how much do I hold in reserve?

I've added another journey. Crazy, right? But stick with me...this one might be worth the added trouble.

I've embarked on a six-month yoga teacher training, and it's intense. The amount and level of physical, academic, and emotional study only seems to grow, week to week. At one point early on I said to a classmate that this might not have been the right time to engage in such a difficult program. Then we started our course of yogic philosophy.

Now I'm chartering more twists and turns in my mind than on the mat. While the training is physically challenging, this journey goes within, and the steadiness of mind I'm building benefits every part of my life.

So this one's a staycation. And there couldn't be a better time for it.

Last week in "Since You Asked," Cary Tennis's advice column on Salon.com, a young woman in a sad marriage suspects she shouldn't be married at all and wonders how to be happy again. The poor thing is caught between the guilt born of a religious family of origin who believe divorce is a sin, and a self-evident truth that she got married too quickly and simply doesn't love her husband.

She even says her husband is a perfectly nice guy. Huh. Sounds familiar.

Tennis's response blew my mind. It validated her (and my!) discomfort as perfectly legitimate and pointed out that leaving the marriage is not a selfish act but instead rectifies the previous selfish act of marrying for the wrong reasons.

Staying in a marriage that cannot be fixed is continuing to patch something that is monumentally broken.

Further, leaving would release her husband from marriage to a wife who doesn't want to be with him any longer, and he could move on. In this case, if the act of leaving is not an act of service to another, I don't know what is.

Cary also talks about how we all carry with us something like a personal truth — he describes it as a package we clutch to ourselves through thick and thin — and suggests that in her case that truth, the thing that defines her and that she is compelled to honor in her life, might be the spirit of freedom.

Perhaps she is a free spirit and marriage in general is not a good fit. Amen. I don't know if he has her figured out, but he sure has my number.

What would happen if I just made up my mind to leave? How would life change for me and for my family? Would I find the inner peace that I lack right now? Would everything magically get better?

I'm not delusional. I know that it would be ridiculously hard. Most of all, I know that it would be a really difficult transition for my kids. They're young and as far as they know, mommies and daddies stay together.

Did I say it would be "difficult?" Maybe I should change that to "horrible." "Tragic." "Life-altering."

"The end of a secure life."

Am I being dramatic? I just try to think of what it would be like if a life truth was suddenly changed for me. What if my house burned down? What if I lost my arm? I can only imagine what it's like to suddenly have everything change.

I know that I would recover just fine. I know the process would be painful, but in the long run I think that it would make me happier overall. Then again, how can I be happy when I cause so much pain to my kids?

What a tangled web.

If I one day suddenly blurted out, "I can't take this anymore. I need a divorce," then it would be a bizarre combination of a huge weight lifted off my shoulders while also opening the door to a bunch of new drama and turmoil. It’s like I know what I want the eventual outcome to be, but I don't want to deal with all the stuff in between.

So what happens if I just make up my mind to leave? The world will be turned upside down. My life will never be the same again. The question then becomes, will the new life be better, and worth the effort?

OK, so you're asking: Why am I still here?

I think I've got a new answer this week: Monkey Branching. You know, brachiation, swinging from limb to limb. Something gibbons do in the jungle.

It's positively evil, emotionally unhealthy, this notion of keeping one hand on the solid branch of home, family and two cars in the driveway, while reaching the other hand out for some branch that may be out there somewhere.

But that's how I plan to go about searching the suburban jungle — finding something, some new guy, new while clinging to the old.

It's not like no one's ever done this before.

In high school we called it keeping another guy on the "back burner," in case some other relationship turned out not to be on the boil.

Alas, in high school, it was just you and the candidates for prom date. Now anyone on the back burner, or, to mix metaphors, any new branch, is going to have to hold not just my heart but my two children as well.

What sort of man would provide such a strong branch? Who would want to? One thing I do know: I won't be swinging on any new branches without my kids.

I know, I know.

My girlfriends, the talk show psycho-bablers, the self-help books, the marriage counselors, all say, "You have to be on your own before you can find somebody else."

Yeah, but I've been on my own before.

I'm no princess, waiting in her turret for Prince Rescue to come along. I've paid my own rent. Worked in Corporate America (high-profile and six-figures, thank you). Dated bigtime in the Big Bad Apple.

It's just that I've never done it with two beautiful pre-school kids in tow.

Monkey branching? Me? The library-helper-mom? The bake sale mom?

Isn't that sleazy?

Maybe this is the real reason I still haven’t filed for divorce: I just don’t feel like it. It’s probably that lazy gene Jill Brooke wrote about.

For a while there I thought, feared, that Ed’s absence was making my heart grow fonder. But as I listened to myself explaining my delay to my (happily married) friend Melody, I thought: What am I, crazy?

OK, the Ed who never minded interrupting road trips to stop at outlet stores, the one who cooked dinner, the one who rescued animals in distress, he was great. And I guess I can admit missing him.

Unfortunately, he shares a body with that other damned Edgar.

The one who spent the mortgage money on a boat.

The one who didn’t quite understand the difference between a wife and a secretary.

The passed-out-on-the-floor-drunk one I rousted to go with me to the hospital when I thought I was having a heart attack. (Big mistake: I should have gone alone.)

These past few months, my estranged husband really hasn’t been any trouble. And I’d like to keep it that way. I expect, though, that filing those divorce papers will change that.

While whining to myself about how I don’t wanna do it, I had a great idea.

There should be a sunset provision for marriages.

Nolo.com defines a sunset law as one “that automatically terminates the agency or program it establishes unless it is expressly renewed.”

I propose that marriages sink below the horizon after seven years, unless the parties take action to continue them.

I mean, you have to renew your driver’s license every now and then -- less often than you must register your car or dog.

Is my marriage to Rob the relationship I dreamed about having when I was a young girl? No. Do I wish for something more dynamic and fulfilling? Yes.

But instead of getting out there and creating a new life, I'm sitting back, waiting. Life goes on in our cozy Boston apartment. We work, eat, and play as usual. Our marriage is lacking (we don't even have sex!) but arguments are few. We easily split bills and chores, and we have many friends in common.

But if I seem certain about staying put, it's only what I'm letting Rob believe. In reality, I'm preparing the way. I'm breaking free from bad habits that keep me tied to Rob: I'm paying my debt and saving my own money. We're selling our car in an effort to go green, but it hasn't escaped me that it also means one less financial entanglement.

My stealthy preparation might be moot. When I arrive at the fork in the road, I might choose to stay with Rob. After all, there is the chance couples therapy will bring us back together.

But if it feels right to veer off and pursue a life on my own, I want to do it without heading straight for the poorhouse.

If I stay, it will be for love. If I go, it will be for an independence made possible by my own hard work.

My husband and I haven't been to marriage counseling for quite some time. I think it has been around six or eight months.

It's not from lack of trying on my part, but my husband's work schedule changed at the same time as our therapist's office hours changed, so it just became impossible to all get together at the same time.

In the meantime, our therapist became more and more interested in me. He didn't even attempt to see my husband anymore, but scheduled me for weekly visits.

I started to back off from seeing him because I got the distinct impression that he either a) had the hots for me, or b) thought I had some intriguing mental issue that he was going to cure and then write a PhD thesis about.

So I'm talking to my pastor about how I would like to get back into marriage counseling and he offers to see my husband and me for sessions. Those of you who have been reading my story for some time may remember that my husband and I started out with our pastor for counseling but wound up with the new therapist when we went beyond the scope of our pastor's counseling capabilities (translation: I tried to leave the marriage and my husband threatened suicide).

I was excited at the prospect of getting back into joint counseling, but when I told my husband he was not too thrilled.

In fact, if anything, he seemed really annoyed that I had asked our pastor for marriage counseling. It's as if our therapist's fascination with me meant that there was nothing wrong with the marriage...just something wrong with me. That means my husband's work was done. As soon as our therapist "fixed" me, everything in the marriage would be fine.

Guess what? I'm not "fixed."

If he does that one more time, I am calling a lawyer. That's it. He's been asked politely, with the proper phrasing from the couples counselor: "Don't say ‘You forgot to get the milk.' " Instead say, "I feel bad when you forget things like this, honey."

I remind myself: "The word 'always' rarely applies."

When he leaves the sprinkler on all night, and soaks the yard turning it into a muddy marsh, I don't always say, "We've got a gusher in the back yard ... again."

Usually I notice it when I'm up first in the morning, as I'm pouring the kids' cereal. So I dash out in my bathrobe and turn off the sprinkler.

By the time he's up and rushing to catch the train, I forget to even mention it.

I don't always use the midnight car ride home from a party to tell him that he raised his voice a tad too loud about Obama in a room full of known Republicans.

Usually I just make a joke: "Wow, you sure told them everything they didn't want to hear, sweetie."

Or, "Remember, these are the people who sponsored us for the golf club last year."

Or, "Maybe you could just tone it down a bit."

Usually, I say nothing, and silently vow to buy a pricy hostess gift, and slip it in front of the host's front door the next morning, without ringing the doorbell.

Why am I still here? Why am I still so pissed? Why am I even contemplating leaving one more message on his turned-off cell phone? So that I can record my fury, my angst, onto that little microchip in cell phone cyberspace for posterity? Lord knows he'll never listen to it. He'll hit '7' to erase it the second he hears, “OK, now, where are...”

Twelve years of marriage and it's come to this. He's not home because he'd rather be somewhere else. With someone else. He denies it but my 'wife radar' is in good working order. I'm sick of picturing who she might be. That's not even the point anymore. It's ABW: Anyone But the Wife. If I tell my girlfriends, they'll all just tell me to leave him, to throw him out. My therapist will again urge couples counseling. Tried that at Year Eight. Lasted the requisite six sessions, with promises to “renew," “refresh,” “re-purpose.” You know the drill.

Make more traditions. Make more efforts. Make more love. Thanks, Ladies Home Journal. Thanks Kathie Lee and Dr. Ruth and Shania Twain. I see it's worked out so well for you.

I could just lie here in the dark. I could start trawling the Internet for a lawyer. I could call that guy from the econ summit, that guy from that party three months ago: “If you're ever free on Thursday nights...”

Or I could go downstairs. Get a jump start making the kids' lunches for school in five hours. Or get the hockey gear loaded in the Tahoe now. Save me a few steps in the morning school hustle. Instead, I swallow an Ambien and knock myself out, just as I hear the car in the driveway. Tomorrow with the lunches and hockey skates. Tomorrow with the confrontation, or the ignoring – I’ll figure it out then, when I sit on the train in my suit from Loehman's. Maybe I'll start shopping at Saks again, like I did before the two kids.

I put my wedding ring back on this week, just to see how it would feel. Sam and I have been apart almost two years, but we never fully split, never filed for divorce, or even for legal separation.

This whole time, I've considered us divorced. I've thought of myself as a single woman and envisioned life on an unknown path.

But Sam never gave up. He begged me to go back into counseling — the same man who once sat in that office, week after week, telling me "he was who he was."

He said, "You met me in line for Grateful Dead tickets. Who did you think you were marrying?"

I thought I was done. Told myself it was just legal fees that kept me from filing. Maybe it was true for a while or maybe it was always an excuse to stay together.

If I've learned anything about myself in the last two years it's this: When I want something, really want it, I make happen.

I never even called a lawyer.

I don't know what kind of category we fit in anymore. The marriage never ended. We still live apart, and the kids split time 50-50 between our houses. I'm still single parenting, but now Sam and I are looking for a place together.

I consider what we're doing a second marriage.

I'm not the same woman who left and I won't tolerate the marriage I had. We've been part way into a relationship and just as far out for almost a year now.

But we have been sleeping together.

The kids have grown re-accustomed to family dinners and camping trips. All along I thought I was waiting for the right time to end it for good. The right time. In the three years I agonized over our relationship before moving out, I learned there really is no good time. There's always a birthday or a holiday or summer plans or some other something to make you think leaving would be easier somewhere down the line.

Never is.
