Do I leave?

I'm sorry you're going thru this! I think as far as packing goes have yourself a little "go bag" just in case but don't go crazy packing. Who knows what will come out in the conversation you have with him tonight. It sounds like there might be more going on with him then you know and he needs to be forthcoming with you. Do you have a sitter for your daughter tonight? I'm sure it will be emotional and she shouldn't see you like that. 

Wait until he gets home and talk. Don't fight don't yell don't argue. Just talk. Everybody says things in the heat of the moment that we don't mean. And by him saying "let's talk tomorrow" could be he way of saying "I didn't mean to say that". If you truly love him and want it to work tell him how you feel. Tell him that if he gets mad or starts yelling you will walk away and not speak until he's done having his fit (that's what I say to mine, lol). And ask him what he wants out of everything. What he expects from you as a wife and you need to tell him what you expect from him as a husband. 

Sounds like you're both under a ton of stress. You guys need to talk it out. But, if his attitude continues, you need to watch out for you and your kid! 

I say give it a little bit more time, just until you both are a little bit more come. It is never good to make decisions when you are in a heated moment. Talk about it with him, and see how he/you are really feeling. 

My husband started acting this way for the most part. He wouldnt call me names or anything but he would come home from work ignore me slam doors and go to our room and lay on the bed in the dark and not talk. He would try and argue about money and everything saying i hadnt done anything all day but the house would be clean even having our 4 kids (2 are mine from previous relationship 1 is his and the last is ours together) playing and running around the house everything was clean but he also has ocd and everything needs to be a certain way so he would argue about that. It turned out after dealing with this for 2 years and me ready to pack my kids up and leave he went to the dr and found out he has anxiety and bipolar depression. He got on some medicine and it took a few months but hes back to the way he was when we first got together he happy hes loving hes joking around he enjoying life again period. I would pack everything yet because you also have your child to think about and you dont want them to get told we are moving and yall move everything then he gets home and says hes sorry that he didnt mean it and you gotta go back and explain yall are moving back. Wait till he gets home and i would just calmly ask do you want the divorce if he answers with anything but a no i think i would go ahead and go because there shouldnt be a idk in there because to me when people say idk or sure or i guess or anything thats not a straight yes or no they know in there heart what they want and ending a marriage is a huge deal so he should already know the answer
