I have issues with people and usually only truly open up to like one person at a time, and then rapidly jump close friends (maybe like 2-3 times a year). But I've been trying to work on myself and have done a lot of healing in the last two years. I made a friend with all the physical characteristics of my abuser and was able to force myself to see past those in order to keep the friendship. 
Now, this friend knows I have BPD. They know I struggle with relationships. And they know I split.

But, after pushing past my extreme urges to end the friendship after some stuff went down, I sent a long ass para asking that we work on our communication to avoid future issues. And this person has continued not to talk to me for like two weeks. It fucking hurts when I'm trying to be rational and not react to my immediate feelings and to be healthy and not just rip through friendships etc but it feels like they don't care. They spoke to our mutual friend, who also brought up some issue they had with him, and sorted it out immediately and is trying to be better with her. But said to mutual friend that they "expected" this from me, so they're fully blaming this on my BPD. Even though mutual without BPD was feeling the same way I am.

The situation is so complicated but it hurts so fucking much, especially because they were my fp for so much longer than anyone has been before and I'm struggling to break the bond. It feels like my mind is going to fucking kill me. I'm so tired of this. And I feel so betrayed.

Edit: Idk what to do. Do I end the friendship or give it time? How do I even get past the fact that they are removing all blame from themselves and putting it on my disorder. On top of that, they knew from the beginning about my disorder and how lack of communication effects me, yet they continue to be non-responsive. AND I'm not being irrational. I ran this past my mutual friend for weeks before I addressed the issues and she has seen me splitting/irrational before. She told me she feels the same about the stuff this friend has been doing. Idk :/
