UF-pike has the right of it.
The other girls gave you good advice.
So to sum up: He doesn't like you the way you want him to like you. *shrug* It happens
Consider it a giftif it were me, and you were really attractive, I would keep you on the hook for my amusement and be a lot smoother about it.
As far as what to do. Justamom is right. Why "do" anything?
He hasn't done you a bad turn at all. He hasn't been mean. And as you said you were the one that "messed up".
So why victimize him for not doing what you want him to?
You don't need a plan unless you are really hung up on him. And given your short history to be really hung up wouldn't be at all rational.
So . . . if he calls and you are up for a late night booty call, or just want to talk: do it. If not tell him you have to go.
Just do whatever you are in the mood for.
