Hi guys,
I have a situation with girl i'm with...today i had a bad vibe because i havent slept for almost 30 hours ( dont ask

)
long story short we went out with my cousin and some other people ( all women ), they were a bit teasy with me, which i dont usually mind but i was stressed, so i decided to move away from them as soon as we get to the bar, i met some guys i sometimes hang out with, reason was not to ruin their fun because i was in bad mood ( to be honest i shouldnt go out in the first place), so she just started to ignore me , like she would offer something to other guys around my table but skip me, or when i said im leaving she was the only one who said if i want to go i should leave, so i said by to everyone, and grabbed her by the waist and said bye, she stared me in the eyes and said ok. now my cousin posted photos of them at the same bar having fun.
now i dont know how to handle myself, should i ignore it, say something, should i text her first or wait for her to to that. besides my friend has a party tomorrow, and i plan on going without her ( she doesnt know about it anyways )
Appreciate your toughts and eventual help.
Kind regards
