Erica -- you did all the right things by obtaining housing and hiring a lawyer - VERY smart on your part and only a woman who is strong and focused on the health of her family will make courageous moves like that!!! The only problem is that he doesn't like it and is beginning to feel the true cost of his choices!! Until you feel more confident, I think it would be best for you to go No Contact as I don't see the point of having any conversations with him right now. If he is penniless, then that is his problem, don't you think? You have a CHILD to take care of and yes, you may have to declare bankruptcy before its all said and done. It could be worse.
Take it one day at a time and focus on what needs to be done just for TODAY to move forward and protect the assets you have. (((Hugs))) Sorry you're sad.
