Why can't I leave....

All my husband does is tell me how terrible of a person and mother I am. I'm essentially just the biggest rain cloud in his life and nothing I do is good enough. He's so emotionally abusive I'm just a ball of anxiety, and depression anymore but when I try to talk to him he just tells me I'm complaining and he doesn't care to hear it because I'm bringing his mood down and "ruining the atmosphere of our house." He'll take our daughter and refuse to let me hold her. I just for some reason can't get it up to actually leave him. I know I deserve better. I just don't know what's wrong with me.
