sounds silly but when you flirt back you should make yourself look really stupid.
This is one way that will make a guy pine for a girl. But its pathetic. This tactic is the one that will get you called names I'm not allowed to list on this forum.
If you want this guy to like you for yourself, then just be yourself, its really simple.
As for what to do... sure, ask him out. If he is too shy and you don't move forward it will never happen. Then if he says no, his loss. It doesn't mean that you guys can't be friends.
Hope this helps.
