I have a problem

So I’m married with one child and we live together and if I were to leave I wouldn’t have anywhere to go. He says he loves me but I feel like I’m unintentionally starting to resent him because of how he acts. He says he loves me and he does do nice things for me but I don’t know what to do because he goes out to check our mail and if he sees that I’m trying to get on a waiting list for housing he’ll flip out and a whole argument will start up and I just don’t want to deal with that. I know most of you are gonna say to “leave no matter the circumstances” but I don’t know what I’m suppose to do. I want to be able to support my son and not have to go through courts but I’m at a loss. He took me in when I was in a huge hole living with my mom with abusive sisters on drugs and he uses it against me whenever I tell him I want to leave telling me that “ if it wasn’t for him I wouldn’t be out of that situation” and I can’t talk to anyone if it’s another guy it has to be a girl but I don’t have any friends. And we work together also because he’s the only one with a car and license so I feel like I’m trapped😞😞
