Jealousy... This isn't something you can get rid of like THAT.

It sounds to me like you really like this boy. Maybe it's just protectiveness (you never know.)

Be careful. And distracting yourself is NOT going to help it'll just hurt either you or the other peson involved.

Your concerned because you care, but until your friend sees what you see, and makes some changes, there is nothing you can do. All you can do is give support as a friend.

Have you asked him why he wants a girl that keeps breaking his heart?

It does sound like you really care about this guy and you may have some hidden feeling. Your hidden feelings is maybe causing the jealousy. Why haven't you expressed how you feel? It sounds like you are a great friend and please just be there for him when she breaks his heart because this chick has a track record.
