For context this started at a party, we were all tipsy-drunk,the girls boyfriend ended up not coming to the party, but all his friends were there.
Me and my friends were just sitting around since were both single and she just came up to us and started talking to us and sending videos of us and also made a group chat with me my friend and herself especially me to a group chat with everyone that was going to the party later on i eventually just sat down with some other friends for a couple hours and didn’t even see her until way later on which then we all left to get some food. I got some cookies and she asked for one so i gave it to her. Then everyone started walking somewhere so i followed, she then asked me for my power bank and i said just give me your phone ill put it in my pocket but since neither of us trusted each other with either of our items we just had to walk next to each other while she charged her phone, keep in kind here we barley talked. Just a couple minutes later i was exhausted so i was just sat down when everyone else started running and i didn’t wanna even move and she ended up sitting next to me and talking to me which i talked back to not be an asshole and just thought it was a normal friendly conversation. Then she was asking to text her boyfriend on my phone since her phone was low and i said sure and just gave her it while she sent voice notes to him thinking nothing of it. Turns out they had an argument so i just gave her phone back and texted the boyfriend that i wasn’t involved in this. A couple minutes later when I’m going home he sent me an angry text asking why i was trying to talk to his girlfriend when i know shes taken and i said everything above i said here. But he just said shes was drunker then i am so it’s my fault for everything.
I understand from his view and what his friends might’ve told him how it could be a completely different story but i thought everything was pretty normal and just friendly so AITA?
