Well young love never lasts forever. I say they might break up in a few months then wait about an extra month then tell him ya like him. Sorry that that's the best I got.
Well, the worst thing u could do, is try to break them up. But i guess u probably already know that. U might have to face the fact that they might never break up, or u might just have to wait a little while. It can be hard but don't be jealous cuz after all, he's only one guy out of amillion others. You'll find the one 4 u.:)
dont try to break them up, that is the worst thing you could do. if your her friend then that should be your priority. just try to befriend him and be suppourtive of both of them. eventualy they will break up, and then you will have your chance. but dont move in too quickly, and you may want to check with your friend to avoid this laeding to a fight between you two, generaly dating a friends ex is not a good idea. so you may want to just forget him, depending on how close you two are. good luck.
