So did anything happen with them / there relationship yet?
Only time I ever caught a girlfriend flirting with another guy via email, I didnt say a word to her about it, she was living with me (my place). I literally put her shit outside, told her to **** off and come get it, she bugs me to this day for an explanation. I just call her a **** and to **** off. Walk away when she approaches me around town.
If I was MARRIED though, I woulda taken every penny and possesion I could before breaking the news
