So, H got an apartment and says he wants to sell the house as quick as possible cause he won't be able to afford both. Looks like I'll be very busy next week! He asked me today if I'll in a few months I'll look back and regret my decision. I told him "No, cause you'll just cheat on me again." He didn't say anything. He's going to be getting counseling from a church pastor. He's hanging out with him tonight. I don't know if he's still trying reconcile or what....
Get a lawyer as soon as you can. I'm glad you stood your ground and helped show him how serious you are about not putting up with his cheating. But now reality is going to kick in pretty quickly. There will be bills to pay, he'll want to see the kids, he'll want to have them stay with him sometimes, there will be issues about the house etc. etc.
So get a lawyer because you need to protect yourself and your children. He can't just "sell the house" from under you like that.
Like they're all saying, get advice from a lawyer. As far as him moaning about not being able to afford everything, the answer is simple:
'You made your bed, go lie in it'
or:
'Shame you didn't think about all that before'
or:
'You're problems aren't my problems'
or:
'Maybe you should get legal and emotional advice, because if I were you, I'd be concerned about myself, not only financially, but also that you're not grieving for your lost marriage - only your lost money'
or:
'Tough'
