Well divorce her. Split the assets. See what you can get to help you move on. 

Bro. You gVe her a ton of chances. She keeps refusing to stop. Fuck that. Why do YOU have to be the good guy.  I’m not saying leave her homeless, but she needs some consequences for the shit she’s doing.  The guy above is right. She has a boyfriend. She’ll be fine. She obviously not interested in what happens to you.  Don’t be a sap.
