So my boyfriend and I just broke up, it was fairly mutual but I consider the whole thing to be my fault. He accused me of lying because in situations of conflict I'd gloss over things, forget what I had really said, and get confused/discouraged easily when faced with tension. We had many conversations about his boundaries, and he told me I had none and that it was annoying to constantly have to repeat himself to me when it came to what I could and couldn't say. Like, I can't post a picture of us because it makes him uncomfortable, but I can tweet about him by name. He told me he loved me, that he wanted to marry me, that I was perfect and I tried asking him if he really meant it all but he said "of course I wouldn't just say that stuff"   
But now that some personal situations have changed, I moved and things have been a big struggle, he says I'm too much for him and that my problems are affecting him too much. Recently a mutual friend of ours wanted to join in on our hangouts a lot more than either one of us was comfortable with ( we would play xbox since I wasn't close), but my boyfriend had expressed frustration with me about lack of time alone and privacy, so I told my friend no. My mistake I made was that instead of saying that it was because I wanted alone time with him I said that he had been frustrated with me due to lack of alone time and that I was trying to maintain this privacy. My friend (who also has bpd) took this very personally and reached out to my boyfriend to fact check whether or not he was actually mad or if I was lying. 

So my boyfriend told me I overstepped boundaries with him by "dragging him into this" situation by mentioning his name and feelings without his knowledge or consent as a cause of this situation rather than just saying I wanted privacy (IE our business nobody elses) and when he asked why this friend was texting him about it I said I didnt know (because i didnt get it) and when he found out I said he was mad he said "Why did you lie to me and say you didnt know when you caused this problem?" Meanwhile my friend is calling me a manipulative liar. I'm not sure if that's really true about me but when I tried defending myself everyone got more mad at me, and I can understand why.  I thought I was just being honest when I think really I was being naive and giving out too much information/not being direct and ended up upsetting everyone. 

I literally don't know what to do or how to cope with this, I think I'm in the wrong but when I tried to start asking for space from my friend they said "Go ahead and run away, you always do this". I feel like I have nobody to turn to in this situation at all
