Love?

[Codine]

What if you could describe to her that whenever she hurts herself, she hurts you? If she loves you she would probably not try to cause you any pain.
If it has gone too far, seek professional help in my opinion.

I don't think it has anything to do with him as a person, I personally think she has quite a few demons, that she needs to put to rest, try getting her to think diffrently. And do diffrent things when she feels angry ect. If still no joy then take her to a doctor.
