I used to have a partner that would pretty consistently diminish me in front of his family, and sometimes friends

He would often straight up call me stupid, and once took me aside to chastise me and make me apolgise for HIS behaviour to his mum because he got upset and somehow I was to blame for that

He also physically beat me and locked me out of our apartment once with only a towel on. I managed to grab shorts and a sweater but had to put them on in the apartment hallway

He would scream at me and grab my arms so that I couldn't get away

He would push me to the floor and lay on me and just not let me get up

He told me sometimes I would have to get to my knees whenever he entered the room. It didn't happen too many times before I left, but I hated it

I remember sitting on the floor and crying, begging him to be a human with me. I left my good job, friends, life, independence to move to his city. I hated it there.

Anyway things are much better but it definitely changed me and still affects me I think
