Good to take in CG's post b/c it largely applies. Your h, blaming you and trying to suck in your dad so your h can drown him too (in addition to you and the kids) is scary.
He has not grown or improved A/K. He hasn't! Don't go down the drain with him, save yourself and the kids while you still can AND DON'T settle for less alimony than you are worth. And remember that IF he does make more money down the road, the kids are entitled to increased child support. So don't worry that you are jumping off the gravy train right before he makes real money. ON the contrary, if he were to make real money and get some more security, I have no doubt he'd divorce you for someone else. I am sorry to say that but I cannot imagine someone with his ego feeling CLOSER to you when he feels all puffed up. He calls you now when he needs his spirits lifted. If he didn't need that, he'd be calling OW all the time. I know that hurts and I could be wrong. I really could be. But for some reason, I feel pretty sure about someone I don't really know. Just mho.
Hope the meeting with the c goes well and we are all rooting for you to be happy. Soon, and at peace.
Good luck j-
