I'd stay in the marriage for my children's sake. I can hide my unhappiness pretty well right now w/ them but as they get older I think they'll catch on.

There's a book by Jodi Piccoult called Mercy, I think & she talks about every relationship being around 60%, 40% & I do feel one usually loves the other a bit more. I give my H everything I think he wants. Plenty of intimacy, I don't touch his social schedule so I could do something of my own, he has many activities he enjoys in fact he's added more to them since we have kids. I think it's bec he knows ill let him go do it & I'm "a great babysitter." His life hasn't changed since kids; mine has come to a stand still. I'm extremely isolated. I feel he has the best of both worlds.
I have been honest w/ him & told him when I'm really down I need you to do x,y & z. He even repeated them in the T session. Last time I was really bad, totally depressed he asked if he could do anything & I looked him straight in the eye & told him "you know what I want when I'm like this." He turned & left saying he had no idea. I don't ask for much. I want to be held. Rocked & told everything will be ok. That's it. Nothing fancy just comfort. I get more comfort crying into a pillow!
Part of me wants more & part of me says I made my bed now sleep in it.
