My girlfriend has very severe BPD, along with a long list of other mental conditions such as Autism, Anger Issues, etc. For reasons I won't be going into I really just need to end the relationship at this point but I'm very scared to. She's made it very clear several time that I'm her "Favorite Person" which I know is a very specific role someone plays to a person with BPD.

She has suicidal tendencies and could break down from very small things, additionally she has made it pretty clear that she might very well kill herself if I'm not there.

Now, none of these things are the reason I want to end it, I knew most of it going in and patience for these things isn't an issue for me. I just REALLY need help to properly do this so she'll be alright.
