and of corse my friend RainBowBow is here to step in with a humores, random comment lol, anyway, I know your feeling. I have a friend who moved to Arizona when I was 10 and we were friends since we were born, he just came to vist and now he likes hanging with my friends, it makes me jelous, but I let it happen.
Its hard to say really, you could just let them talk to him on the computer or something, phone maybe. Jelousy is so hard, I know, im still jelous of this girl, who is dating my best friend who I fell in love with, she doesnt diserve him, but I just hold my tounge for everyones sake. I know its hard, but you might want to just let it go, you might be wrong, they might just wind up talking once, or being friends, but if they do lead to a relationship, then that is going to be hard as well. Maybe before you let them talk, tell him how you truly feel about him, then see what he says and does, then take it from there. I hope that helped, PM me if you need anything else. Good Luck
