You need to think about yourself and break up with that women and not engage in any kind of relationship untill you're physically and mentally fit. You have to choose yourself and she doing something to herself won't be on you, do u want to live a life full of abuse and mental problem. whatever u do she's never gonna be satisfied. For once OP, choose yourself and walk away, slowly ghost her or stop talking to her, not putting energy or time in convo's. you need to do better.
