I don't know what to do anymore

Okay me and my boyfriend have been together for a while and we have a problem his family his parents won't let him do anything he can't leave the house he has to babysits his siblings and he doesn't get to be with his friends and me if he does he has to lie about it and he has to. It everything for his family never gets o have fun and he almost never gets to have fun and it's getting in the way of our relationship and we are looking for alternatives for this problem and she also supports him financially but she makes him feel like shit and wants to kill himself he would have to give up school to live freely of her but she still would control her Any advice would be appreciated
