My husband asked for a divorce, changed his mind but I’m not sure I want to stay

My husband asked for a divorce while I was trying to communicate with him. His communication is way off. He doesn’t like to do it. He is never wrong about anything. Doesn’t want to help much with the new baby we have. I’m tired with taking care of the baby while working from home, laundry, upkeep of the household, homework with our nine year old. Well he baited me into an argument the other night. Told me that we are not good for each other, he wants a divorce and now I can finally stop crying. I’m battling post partum and I’m not sure if he is either. I have begged him to do counseling because he does not listen to me. He refused. He said again he wants a divorce. Im looked at apartments in South Carolina because we can’t afford to stay in Georgia with my income alone and he said he wants me to take the girls. His mom is there and will help me. Today he says that he changed his mind and that he wants to try. I don’t know how to feel. I’ve spent the last few days a crying mess because I’m a good wife. And I’m not sure I want to try. I’ve never used the D word under this roof. But I feel like he should have been sure before saying it. Because if we split, at least I will have help
