What about him? He's a loser if he waits till she's unavailable then puts the move on her. Manipulative?
As far as the 'I never stopped thinking about her' I'll say this: I had a girlfriend from high school that was similar. Never got into a serious relationship because she was too messed up then. But I also never 'got over' wondering if she and I were better suited to each other.
My counselor always said to me "You were holding on to a fantasy of show she 'was', not a reality".
