NTA He's not forgetting, he's gaslighting. He's only pissed off because you proved that you were right and that he was wrong, and you proving that he is full of shit means he wants that proof gone and any blame on him gone.
AITA for screenshotting my boyfriend and I's convo
My (23f) boyfriend (24f) has a tendency to forget things, especially when it comes to arguments and things he's said or promised. It's gotten to the point where he says some pretty nasty things and calls me bad names and says stuff that felt unforgiveable at the time, but then we we gloss over it and move on. But whenever I bring them up again (usually a few weeks later) he denies ever saying it/doing it/promising it.
I feel like I'm losing my mind because I definitely do remember him saying these things but he denies to hell and back that he ever said them. One time, he promised me he would act better and never call me (blank) but a few months later, he breaks that promise. Then he says he never promised anything to me because he's not the kind of guy to break promises.
And I got fed up and I knew this would happen so I started to screenshot every bad and good thing, and every promise he said to me and I kept them in a little locked folder. I never looked at the folder until recently when we fought again--we got into an argument and he denies ever saying (blank) and promising he wouldn't do (blank) etc, so then. I send him the screenshots
Iive never seen him so angry (this is through text). He tells me that he doesn't feel safe or secure around me anymore because he doesn't know who I'm sending those screenshots to (which is nobody but I can't seem to convince him of that). He says our trust is broken because he can't say anything without me using it as evidence. He says I'm just collecting fuel for arguments now.
And I promised I would delete them, and I did, and he hasn't spoken to me for a few days now. I've apologised but I don't know if what I did was right or wrong. I know I shouldn't have screenshoted without his permission, but I've sent over our chats before and he didn't get mad (this was a group trip where he was asking about locations and I sent it to the people we were going with and then I sent their replies back to my boyfriend, and he seemed completely ok with it then).
Sorry for rambling, but am AITA??
