Any thoughts or ideas/insights would be really appreciated.
Have tried LC but it hasen't worked for me. I was fogged yesterday , started by being guilted into conversation about how well he is getting on now and some information about his sister. It feels like it was a smokescreen and the window was opened for the barrage of emotional blackmail, blame and twisting. Subsequently I haven't eaten all day through feeling nauseous and guilty.
I also feel angry at times as yesterday he decided to have a go at using the death of a close relative of mine for his own selfish gain/ try and beat me into submission.
I understand this is an illness but things often feel so calculated that its mind bending. He actually dosen't care a tiny amount about my feelings except to try and make me feel bad (and thats what it feels like).
I can see he is in for a recycle (which has never happened after I ended it) and I can see how the

were easy to miss at the beginning of the relationship. It is convincing, easy to doubt yourself or believe the words.
I don't know what to do now. I spoke to my mother about it and a friend but its like people keep applying logic to the illogical. Like when people talk about boundaries. I KNOW about boundaries but that for me is why BPD is impossible to deal with. Boundaries are in my experience a trigger and a challenge to my uBPDexboyfriend, he rail roaded them, very often using in his eyes "caring motives". Like banging my door at 4am because I had said I wasn't availiable that evening etc etc. He said he was worried, as even if I wasn't availiable on the evening apparently I should have been answering my phone at 3.00am.
So NC it will have to be, do I tell him? . what difference does it make anyway. It is another boundary that he wont respect. It feels so hopeless.
