it is weird how there is such consistency in guys feeling like they would betray their friends if they would take their ex. you know what man, what is in the past is in the past. i would go hook up with her again if i were you.
Well she's his ex. He let go of her by will. Does this mean she can't see anyone else? So what if you guys are friends? He should respect your as well as her desires. If he doesn't then he's no friend :)
