So much self work is needed on both parts to even attempt at have a semi normal relationship. Take all the mental health issues out of it.

Being aware isn’t for the faint of heart.

Sounds like you found someone with high narcissist traits. If someone lies, cheats or even hits me I would never block them when I know they are panicked of worried about something I have control over to smooth out and make my partner feel safe.

I sometimes question if I’m borderline. I can love hard, but if push comes to shove and I’m triggered. You better come double barreled. Because I have a tongue of ice and it can get cold as fuck. Lol. Not proud of it, just saying.
