There's good advice, Op and then there's this. Let me just start by saying, don't listen to people who come here just to say every little thing is abuse. They'll convince you that most of the world is out to get you and you should run away from all your problems and drop your friends and family. Them aside-

Communicate with your partner. Too many times do I see people asking for advice here when they haven't done the first step of healthy relation 101. You need to tell your partner partner these things are uncomfortable or when they are upsetting you. Nobody is a mind reader. She may react badly, that is the unfortunate reality of being with anyone, bpd or not.

I believe in working through problems but I am reading into you here and it does feel like you do not like her much considering you're asking people on reddit for advice. If this is the case, please break up with her and leave her life for good. Don't drag it on, don't make her suffer, just politely end things and move on.
