I hope I'm doing this right, it's my first time on one of these.

To the girl who orginally posted, and the girl that's 6 months with 2nd child, I too am in the same boat. My husband went through this last year, questioned whether or not he loved me anymore, and I was heartbroken. It completely surprised me, even though we had problems, I thought we were ok. He started counseling alone, wouldn't go together, and we separated. My 2 year old and I moved to my parents, but after about 2 months, he called asking for another chance.
We reconciled, and things truly seemed to be on the right path. He swore he was over it and would never leave us again, and here we are, almost a year to the day later. I have worked really hard on the things that I did to contribute to our issues, which, while aren't perfect, are tons better, but I guess it wasn't enough. I was the only one working, and am now 5 months pregnant with a baby girl.
I don't feel equipped to handle this right now. At first I was in denial, called a counselor and made an appt for us together, thinking it would be ok, that he is just having a mid-life crises or something. The more I am honest with myself, I think - who would do this to someone they love? Who would choose the moment when their wife of almost 5 years is 5 months pregnant with their second child to revisit this?
I feel myself wanting to shut down and let it go, but I know that for the kids, and for me, I can't. I'll try to wait out the counseling, the only problem is, a marriage is hard enough without only having one person fight for it. It takes two sets of hands to hold on when things are tough, and I just don't know what to do. I can't fake it and wait, and everyday feels like an eternity now, waiting for him to say something to make it all better or erase it all. I keep thinking 'he's just not that bad of a person to do something like this,' but maybe he is...
Pray for me, pray for strength and forgiveness for me, and for my babies.
