" People don't drfit apart for one specific reason. Well, you might be able to find a reason, but you could come up with one only after you made up your mind, a tired excuse tacked on after the fact. If their hearts were still in it and their bond was threatening to sever, you'd think one of them would step in and try to fix things. When no one does, you you know the bond has already been broken.
