Flirting

Girlfriend flirting and grinding with a guy in front of me!

So we were at a bar the other night and a guy comes in and sits next to my GF, I go to the bathroom and come back to see she has started a convo with him. This is fine but it turns into flirting, THEN she turns her back to me for several minutes so she can talk to this guy...So we move to play darts and the guy shows up and starts flirting w her again and buying us shots. the whole night he is rubbing against her and flirting big time. At the end of the night she ask to dance with him and she grinds all over him and has her arms around his neck looking into his eyes... I dumped her ass that night, I don't feel it was out of line, but I want to know what some of your opinions are. Thanks!
