hi dollface and

I struggle to know if any of the relationship was real.
i think many of us struggle with this. the truth is, yes your relationship was real; all of it. the good and the bad. you were there, you experienced it (perhaps differently than he did), it happened. it helped things sink in for me when i realized that all of it, the good and the bad, were simply not sustainable, for a variety of reasons. it also helped me not to separate the good from the bad. all of it was real.
are you looking to reconcile the relationship or leave?
ps. tread lightly watching youtube videos. BPD is a spectrum disorder, and someone on the internet claiming to have borderline personality disorder can only share their limited perspective that may or may not apply to the person youre describing.
