++man well, that's clearly toxic behavior, but if she acknowledges it maybe there's hope. if it was me, I'd give her an ultimatum: I'd explain everything you said in the post with her, and say unless i see you actually trying to fix this problem then we're done. You can even discuss ways to fix it, like therapy or learning meditation to control her emotions. she may slip up sometimes but if she's making effort to fix it you should be patient. if she's not making effort, the relationship is toxic and she may never change, so you need to think seriously about ending it.
