I wonder why anyone who suffer from BPD would be self indulgent with their emotions(could it be not being confident?) is there a way you could admit your true feelings without previous shame or guilt(assume with an ex you certainly have feelings for) and he has no ill intentions but there has been some previous/old betrayal(not due to his own actions entirely but given the fact someone simply denied their feeling they had for them because they were guilt and this lead to similar reaction that caused anger on the BPD person)
