<human>: Can you summarize the given text in a few sentences?

I am with my GF of 6 months, everything was just absolutely flawless, like no problem whatsoever, we planned the wedding, kids etc. 

So we were at a party, she wanted me to meet with her 2 best girlfriends with their BFs. So basically we were 3 couples. We drank a lot of alcohol. Out of nowhere I hear my GF saying the guy next to me "I would kiss you, but my BF is here". I was speechless for like 10 seconds and then i realized what I have just heard. I was like "WTF?". I have taken my GF to the bathroom and have talked with her there for 2 hours about it.

Her explanation "I wanted to see you jealous! Because you were looking horny (hard to translate, not a native speaker) at my older sister, just because she has large boobs etc.". "you are never jealous!" "I didnt want to hurt you!" "I would never say that if i knew that it would lead to this" "It wasnt meant like that, i would never do that, i would never kiss him for real".

I am now back at my place and she is sending me text messages, that she loves just me etc. and she also tried to kiss me a lot when we were getting out of the place.

What would you do?
<bot>: My GF told a guy next to me "I would kiss you, but my BF is here". What to do?
