One of the girls I'm having sex with just started talkign to me on facebook about Christmaseve and the party we attended.
She explained me an incident that happend.
Apperently before I arived some dude bought her a drink, she accepted his offer.
And each time he passed by he touched her so she told the guy that she was going outside to ditch him.
The guy responded with OK and gave her a quick kiss on the lips,
She had no idea wtf just happend.
So she decided to tell me what happend before anyone else would start some rumours ..bla bla bla
and now he is facebook texting her all the time
So guys,
-the fact she didn't push him away ( even though she told me the kiss only lasted half a second ) kinda worries me, is she playing me

- should I kick the guys ass , I'm not dating her but everyone knows she is with me

I don't care abouit the little kiss, but the guy touching her all the time when accidentally passing by, thats just creepy.
- Should I fuck his ex girlfriend ?
And for the record, when she told me about this my reply was;
"Ye, someone already told me. I hope his kissing was better than his seduction game

"
I've never been in a situation like this before and I want to know if I should take action or just laugh it off
I can walk away from this girl at any given point, it's just that it worries that I have no clue what to do :p
Happy Holidays !
