Just that really. I'm not with this person anymore, but he would always use things I've told him about myself against me in arguments.
Example: I told him about my absent father, and how not having him in my life affected me. In arguments he will say : " well even your father couldn't be bothered to see you.."
Or I would tell him about a past relationship and how tight that person was with money. In an argument he will say : " what don't you go back to your ex who couldn't even buy you a meal .." this is constant.
It makes me not even open up to future boyfriends tbh, in case they throw it back in my face. Anyone else had a partner like this?
