Basic details, shes 24 im 23, just started a LTR 4 days ago (was a plate for 4 months).

The context of the night is this: Yesterday we were out drinking with her girl friend, just us three, having some light and fun conversation, the relevant information about this place is that its a really crowded restaurant-bar: the person in the next table feels like is in the same table, like 2 feet away.

Next to us were 2 guys, and this one guy kept looking at her, no problem, but she also kept looking at him. The fact the we were so close make it worse than just looking from the distance, I dont find it ok.

Maybe that I could ignore, but it doesnt end there, since we were so close every conversation can be heard, she complimented his watch to me. Then started to do some shit that I can only assume was to give him some clue about her Facebook information, so instead of saying "in my job" she said "and thats how things are in my Job, work-place-by-name". She also mentioned obnoxiously about doing a check-in in fb and that she is gonna TAG her friend in it. And kept bringing that up. She also later on said, "not like that, Stacy Lambert (fake name of her friend)". As I said he was looking at her, so she knows he is paying attention. Later said again, oh I forgot to TAG you Stacy.

I confronted her later that night about the "eye contacts and how she tried to get his attention" and at first she tried to deny it and then admitted and said it was not ok, and a discussion started about how I also look at girls (not the same), and ended there becuase it was getting late. I didnt wanted to sound crazy and that I imagine too much, so I never mentioned anything about the tricks she used to sneak her fb information.

Today is a holyday but I canceled a planned trip, I couldnt wrap my head around those shitty tricks, I thought thats a deal breaker for a LTR. In the middle of a discussion over text I finally mentioned how its not ok to deny, especially because I was aware of everything she was doing, she apologised profusely and said I know its not ok and will never happen again. Then directly mentioned about how she tried to give him details to find her, to see if she denies and for my mental sanity, she didnt deny just ignored it, but asked for forgiveness.

What would you do in this situation?
