AITA for being mad that my mom got back with her ex?
i’m 13 and my mom is 43, i know a teenager shouldn’t be telling a grown woman what she should and shouldn’t be doing but hear me out first
the first time i met this guy was when my mom invited him to our family vacation, before this i has no idea she even had a boyfriend, but i didn’t complain because being with 3 kids on vacation alone would’ve been miserable. (my mom let me and my sisters friend come with us) the problem is i barely did anything with my mom the entire time we were on vacation, we went to the water park together once and that was it besides a few short conversations. i don’t think this was her boyfriends fault but it’s still something i wanted to mention.
after the vacation, her and her boyfriend seemed fine, until they started arguing almost daily about stupid shit. her boyfriend (who im just gonna start calling L) would constantly accuse her of cheating, which would then escalate to him taking her things with him when he left and not give them back until my mom threatened him.
after awhile of this they ended up breaking up, and during that period i told her how much i hated him and how he was incredibly toxic, she agreed with me, then like a week later got back together with him. he hadn’t changed one bit and the cycle repeated.
she broke up with him again, and again, i told her how much i hated him, but this time told her i would be seriously pissed if she got back with him because she KNEW he was a bad person. she also told me during this conversation that he had a problem with drinking and was fucking another girl (who also had a child) when they would fight.
she got back with him again, (this is when i started getting upset with her) then they broke up again, then they got back together, when they got back together both me and my sister tried talking to talk to her about it and her response was something along the lines of “im the adult, not you guys”
after that i had pretty much given up on trying to tell her that L wasnt a good guy, because she clearly wouldnt listen to me. recently they got together again and L started coming over again, and a few days ago my mom came into my room, handed me a credit card and said it was from L??? when i asked why all she said was “because he loves you”, i asked my sister if she got one and she didnt, so now i just feel really weirded out about it. (i ended up giving the credit card back because i didnt want it)
ive been kind of giving my mom the cold shoulder since he started coming over, and i kind of feel like im the asshole, but i also think im kind of justified for it, AITA??
sorry if this is formatted or worded weirdly im really tired at the time of writing this and i just want to get second opinions
edit 2: i forgot to mention but she has a history of this, she recently also started speaking to her ex fiance again after he tried to break into our apartment in November (i also told her to cut contact with him again but she didnt listen)
EDIT: SORRY IF MY REPLIES LOOK WEIRD MY REDDIT IS BEING WEIRD 💔💔💔 IM 90% SURE I REPLIED TO THE WRONG PERSON SOIF THAT WAS YOU IM SO SORRY
