Upset and in panic. Please help!?

Tonight, I did something that made my husband mad. He said he would go spend the night at a hotel. I convinced him that was irresponsible to leave your family because you're mad. He went out to have drinks. Before he left, I apologized for my part in things. When he came back, he was still mad but I was no longer apologetic. He threatened divorce (he does this often) saying he wasn't filing because he couldn't afford it right now. I shrugged and said I really didn't care anymore (which I never do...it usually ends up with me begging him to reconsider). He then told me he would go for full custody of our daughter. I am a stay at home mom- and a good one. I asked why he would take his child from her mother and stick her in daycare, and he said so he wouldn't have to pay child support!!!! I was appalled, but I'm also really scared because when we separated before, we actually did go through a custody case. I'm so upset, and so scared that I'm frozen. I have a counseling appointment tomorrow- he says "maybe" he'll be there, but that he has no intentions of changing...ever! He says I'm the one causing all the problems. He also said I should just move out, and as early as tomorrow would be great. He knows I won't, because I really have nowhere to go and no money. He has gone to bed now. Is this a control freak thing? I don't even know what to think right now. Please help!
