Anyone experienced dating a BPD person?

Every couple months my boyfriend cycles in our relationship where I’m good and he’s glad to have me then one small flaw he picks up, he breaks up with me and I’m not “ good enough” for him.

Every year, around this time .. I go out of town to see family out of state back home and he picks out flaws in me and finds reasons to break up with me and justifies to himself why I’m not good enough for him. But then a few days later tells me to just stay and that he doesn’t want to break up anymore

It’s as if he projects all his subconscious fears onto me.

For example:

Lately I’ve been noticing that this last cycle we’ve been in has making me feel depressed and exhausted. So , then a few days later he uses whatever he thinks he’s making me feel as a This new flaw of what he feels about me and why he needs to end the relationship. He will say things like ,

“IVE BEEN SO DEPRESSED lately TRYING TO MAKE U HAPPY AND WORKING HARD FOR U AND U DONT WORK OUT HARD ENOUGH , NOTHING IS EVER GOOD ENOUGH FOR YOU, I NEED SOMEONE BETTER. “

It’s like he projects HIS PERCEIVED SHORTCOMINGS and EVERYTHING GETS FLIPPED ONTO ME!!
