me and my gf both 20 been dating for 1.5 years and living together. my gf recently joined a political (nothing crazy just workers n womans right politics) organization because it made her feel safe. thats all fine by me she can do whatever she wants. After joining she came home very late from one of the guys house in that oranization, didnt answer my phones or my texts for 2 hours, she said "we were doing a meeting so i left my phone in another room". i got irritated after this. and today one of the guys in that organization was acting too close to my gf like flirting but not directly, checking up her, and i saw him touching my gfs hips while walking. so i found his account and i said "I suggest you stay away from my gf" no threat or anything.
She said i ruined her reputaion and made her a joke for my masculinty. now she wants to take a break from relationship and calls me asshole. am i the asshole?
