Struggling

Hello, I don’t know what to do. I currently had my son on 1/31 and have a 5 year old and a 16month old. I found out that my boyfriend has been cheating on me with my “friend”. When I confronted him about it we got into a huge fight and he told me he wants me out of the house. But I don’t have anywhere to go, don’t have any money to move out and will be on maternity leave for at least 12 weeks. He has been very emotionally, mentally, verbally and financially abusive towards me. Recently he stopped smoking weed and now he is drinking and getting drunk most nights. When I say anything about his drinking he gets very angry and tells me to shut up about it. I had a c-section and I am not supposed to drive but this morning when I tried to wake him so he could take our oldest son to kindergarten and middle son to daycare he got really mad at me yelling and calling me names and saying that he doesn’t care that he wasn’t getting up and that he can be late. My point is now it seems like he would rather drink and go out with friends than stay home and help with the boys. We split up but he is still talking about things he wants to do in the future but I need to move out of this house with my boys. I have tried calling around to places that help with housing and helps with DV but anyone has waitlist for at least 2 years. It is starting to affect my son, he has been acting out at home and at school. His dad hasn’t been home that much the past week and he does great when it’s just me and his brothers but once his father gets home he starts being mean to me and his little brother, will yell, won’t listen. I’m stuck and he knows it. What can I do to help my son until I can get the money to move out or what can I do to while on maternity leave to make money without him knowing??
