i cant tell whether or not i'm being taken advantage of

I have anger issues that stem from years of abuse, verbal, physical, and neglect. I've done a lot to grow but I still make a lot of mistakes. I'm 19

I got in an argument w my bf today. It was thankfully pretty small. I'm out of my toxic home and living with him in a new state. My anger has been so easy to manage because I'm not constantly reliving my trauma.

He insisted I was cutting him off the whole time. I genuinely can't remember!! I can't remember what I said. I can't remember how I acted. I get so frustrated cos it wasn't even 5 minutes after the fact. I just feel so dumb like, it sounds so bad to jhst say "I can't remember!" I'm not copping out I just can't remember no matter how hard I try

All I know is I get so upset because I think I'm not the one at fault. No one's at fault really but I don't realize how I acted was inappropriate, because I can't remember.

I'm just frustrated bc I can't tell in these situations if I'm being taken advantage of

I also have truly bad memory. I forget things, bad things, literally minutes after the fact. It's so shit
