Is it okay?

Marina
Hey ladies so last night was ruined because I got super angry at my boyfriend because he was talking to his bestfriends girlfriend which they have been friends for like 6 years or whatever, I don't give a shit if they were talking or whatever, but I just want to know if I over reacted because he touched her thigh while they were sitting down and started full on flirting with her right in front of me while I was talking to my friend.
The fight nearly caused us to break up. Just wondering if I over reacted or whatever.
