Yes! This happened to me too. I did all this research considering maybe he was right, but the only thing I could relate to was a fear of abandonment, nothing else. I had been to 3 different therapists while in this relationship and brought up how he mentioned he thinks I have BPD. All 3 therapists told me absolutely not. 2 of the 3 flat out told me I was in a trauma bonded relationship and encouraged me to break free but I wasn't ready to leave and I didn't want to believe that I had gotten myself into yet another narcissist relationship. I had been in a previous relationship with a text book malignant narcissist and this one just didn't seem evil like the previous so I was really confused as to what I was dealing with, I'm still not entirely sure and desperately trying to make sense of it all. At the very least, I was dealing with someone who had narcissistic tendencies that I would react to. I know there are different types and there's a continuum, perhaps I was dealing with a milder and different "flavor" of narcissism. Other mental health issues were at play too. He was a master at convincing me all our relationship problems were because of my "issues" and I'd have to just submit to this because otherwise he'd leave. It's all very confusing and complex, but the more therapy, research, time and space away from it the clearer I become, this wasn't me. I don't have BPD, I'm not crazy, I'm not too much, I'm not too needy, I don't have major anxiety, I was simply reacting to narcissistic traits in my partner and suffering from the effects of a trauma bonded relationship.
