Honestly she sounds like a nightmare. :/ I had an ex with anger and drinking issues and ended up staying for almost 3 years before finally leaving. The difference here is that she is financially taking care of you, and that complicates things. If you have any family or friends that you can stay with until you can get back on your feet, that might not be a bad idea. I can tell you from experience that people with these issues are not likely to change unless they WANT to get help, and that doesn't seem to be the case with her.
