Every time Sam and I walk into a potential rental house, the muscles in my body clench. Instant tension under my skin. And I'm aware of this.

There's that saying: The body doesn't lie. And a friend once told me the body is the brain, you can't separate them out. I spun for months on that one, trying dissect the paradox of its truth.

But I get it.

When I have a rough day with my kids, when my patience is short and every touch torture, it's my body making life so hard. When my body is tense it has a strangle hold on my brain. My mood is short and ugly. When I'm relaxed, anything goes and I can go with anything.

Maybe it's the kids that trigger these house hunting freeze-ups. The way an empty house brings on instant off-the-wall insanity and they're moving loud and fast and relentlessly.

It was like that when I looked at my little post-separation apartment with Lila, too. My mellow 22-month-old ran screaming around the hardwoods. The moment we walked out my sweet quiet baby was back.

Could be the kids I'm reacting to, too. Could be the reinvention of my marriage with Sam.

Right now my biggest fear is this big thinking brain of mine with its fat-mouth ego could have an agenda totally at odds with the rest of me. The whole of me. And if I'm not careful I'll make a wrong turn back into oblivion.

After 10 years of marriage and another two of separation, it seems like this whole stay-or-go thing should be clear. Especially since I've agreed to stay.

My brain says nobody loves you like he does, baby. And nobody will ever love your kids that way either. When I'm quiet I can hear my soul whisper in agreement.

So why is it that my shoulder is rock-knotted and I can't turn my head?
