Penny, I am so so sorry to read about your sitch. I can't begin to imagine what you're going through.
Please give yourself a big pat on the back for keeping a house going with two young kids, one on the way with all this emotional upset.
I would suggest even if it takes SUPERHUMAN strength DO NOT look at his FB profile. In the past month or so my H and his GF has taken to "checking in" where ever they're at: coffee shops, restaurants, museums, etc. I think it's childish and I have my own opinion on why the GF/OW do it, but that's beside the point. Stop looking. It's only hurting you. I also told my friends and family members when they brought it up that I don't want to know. So they don't talk about it with me.
So if I'm right he's spending some nights at home and some nights out and you never really know when? That's tough I don't know what to say about that.
Don't push...it will always end up pushing them farther away. I would say just wait. Try as much as you can to focus on you and the kids and enjoying the baby.
