@ Pink Pggy- Maybe he just TOLD you he thought she was ugly and fat as to suppress your suspicions. I left an abusive relationship of four years and my childhood friends ditched me and still hang out with the fat fucking bastard. Apparently my standards are too high when I say "dont date my ex's, and don't stop being my friend for no reason". It is no longer any of your business whom he decides to date. What if your ex is the one and only for your best friend?
Since your Ex was once your friend you can think of it as your friends are dating each other not your friend and an Ex. It's almost like you want to sabotage the chance of others finding potential happiness and love because you're miserable seeing what you once had. It's ok to be mad, especially if you still have feelings for the guy.If you were a true friend you wouldn't be so selfish Ditto. Even if a guy 'liked' my girlfriend and/or either some guy liked her, he was off limits; not only because of what I just mentioned above, but I'm not going to be anybody's second choice anyway... But you have to understand that you and your friend obviously have similar likes, or you probably wouldn't be friends, so liking the same guy can easily happen.
