Hi Katie and welcome. I’ve added a trigger warning to your thread as you’ve discussed instances of abuse. It’s nothing to worry about, it’s just to ensure that any other member who might find this difficult is able to avoid your thread.

Can I ask why you think that her behaviour could be because she’s mentally ill? People around the world have these unhealthy kind of relationships - some have MH issues, some not. Tbh, it seems to me that you are both not particularly good for each other and would probably be better off without each other and being in a relationship like this is not going to help you deal with your addiction.
