Growing up

So this one person lets call them bevon was dating this girl name belissa and after a year and some they broke up because belissa fell in love with bevon, but bevon did not feel the same way. Now bevon is being a dick and not letting go of belissa because he is immature that way and loves the single life, but still is really physical and hangs out with belissa when he has nothing else to do. He is essentially playing belissa like a fiddle and belissa is "helpless" and can't stop it from happening no matter how much she wants too. It is a really shitty situation and bevon and his immaturity is loving it.

So the breaking point from a 3rd person perspective was when I was out with both of them and after a few drinks belissa was drunk crying because of how shitty the situation is for her and bevon felt bad, but the very next day, everything was back to the way it was like nothing had ever happened.

Essentially, I do not believe bevon has ever been told straight up about how immature he is (which is probably why he has some other attitude and habit issues) and its getting to the point where I might just have to do that favor. Bevon let go and stop being a douche! Belissa is not a fiddle for you to play with.
