I told my girlfriend she wants to break up with me but doesn't have the guts to say it

My partner has BPD which has made things difficult at times. Most of our two year relationship has been incredibly loving and fun, but there have been a few "hotspots." The worst was about this time last year when she called the police on me in the process of breaking up (for the record, calling the police was totally unwarranted (I was not nor have I ever been violent or aggressive in any way). I bring this up to get us to tonight: I was listening to a recent Supreme Court case on my phone while making dinner and she felt the sound was violating her space. Within just 2 or 3 sentences things escalated until she was throwing about $150 worth or groceries around the house--some of it in the dirt outside, some of it in the garbage can, etc. I used some not so gentle language to tell her to get out because the last time she was throwing stuff was when she called the police.

Deep down I feel like tonight's events are the latest in a several months long string of what are either "tests" to make sure I still love her, or just random crap she pulls to make me not want to be with her. I feel for the last couple months that everything i do irritates or disgusts her in some way. I think she wants to end the relationship, but she knows that im really good for her. So the only way her brain can reconcile that is to make me the one that pulls the trigger so she can feel like the victim.

In short, she left and im not 100% where she is right now. We had a string of texts where I tried to say i was sorry for not being sensitive to her mood but also implied that I was expecting an apology from her as well for her behavior. I assured her she was welcome back home to sleep in her own bed as long as we agreed that the situation had cooled down. She was incredibly terse and unresponsive in general. I a certain point I said what I was thinking--that she was looking for an end to the relationship but was pushing for me to be the one to do it. She called me crazy and some other choice names, but definitely didnt make any overtures towards reconciliation.

So......AITA for telling my gf that I think she's trying to get me to break up with her?
