This question might be a bit unusual but, well, here goes. I was diagnosed with BPD by my year long therapist a few months ago, and all of this happened in the middle of a very destructive and even emotionally abusive relationship I was having at the time \(that I have not managed to escape yet\). 

Basically I did a lot of reckless things and reached many highs and lows because of this person who I strongly suspect has... some emotional problems going on, whether it's BPD or even narcissism. I have been manipulated, gaslighted and put down by him in many occasions and he's unstable in what he wants and feels, just like me but he becomes callous and withdraws, or prefers having control while I'm constantly fearing abandonment. I have recognized splitting in him. 

Buuut... I'm not a saint in the dynamic either, I swing between hating and loving him and overall it's the worst thing in the world, I just wanted to know if this very self\-destructive situation actually made me temporarily exhibit traits fitting of BPD. Maybe some kind of side effect of everything he is putting me through. Because as much as I have identified with BPD in the past I feel like I do not have it strong enough for it to be really me \(this and my entire family doubting me and claiming I'm looking for ways to justify my dysfunctionality\). So maybe he is the one making me unstable.. even though I have been unstable in the pas, just never to this extreme. Or perhaps, is it just the perfect situation for my BPD characteristics to flare up and come out?
