Was your pwBPD very jealous about everything?
My pwBPD would be jealous of my past relationships and my friends, honestly anything that happened before them or my life outside the relationship. I had to downplay my life before them to make it sound like I was so miserable until I met them. I had to pretend that my memories or travels were mid. I couldn’t even show them pictures or bring up something I did without them getting jealous and take me hours into comforting them. They would be jealous of my life outside of us and would guilt trip me into not doing other things. They wouldn’t go to places or do things I have already done in the past because it wasn’t with them. They would bring up my past relationships thinking I liked my exes more.
