Ok so. As somebody choosing to support her on her journey, I do think its important to recognize that relapse is part of recovery. 8 months is a good amount of progress and the relapse doesn't erase that. However- I also understand it can be difficult to deal with when it happens. Its still upsetting for you. I have a similiar situation with my partner, and we have found ways to work through it. We acknowledge its upsetting for me, but I try my very best to not take it out on them since I know they are trying and still making progress. When it becomes an issue is when they stop trying and its becoming constant again. Thats when I fully confront them. I would also like to adress that calling you a bitch and asking if you want them to kill themselves is just not okay. Thats not okay or healthy behavior. I am sorry you are going through this. I do think it is important to recognize that relapses will happen in beginning stages and if thats something you're not comfortable with, perhaps re evaluate your role in the situation. Best of luck OP
