22M with 20F LTR of 10 months, she was a plate for 6 months before that. We've had some ups and downs, but I've kept a good ratio of AF/BB and she is a sweet girl, lots of sex, surprises me with nice gifts, etc.
Last night we were in a parking lot drinking with a couple friends and we went over and introduced ourselves to a group of gay guys. They were nice, but long story short my gf flashed them to show off her nipple piercing.
I played it cool and acted like I didn't care at the event, but later that night I told her I was disappointed in her, that I was shocked that she thought that was okay to do, and left her house. I haven't responded to her since.
Is this a nextable offense? I honestly never thought about this type of scenario so I'm just not sure. I'm not jealous or concerned that a few gay guys saw her nipple. Its more the lack of respect and boundaries she showed for the relationship.
