If you really want this girl as the guys said you have to play it cool.. for what ever reason she did not want to go with you at that time..
No does not have to be forever just dont sound like a stalker.
Buy her a drink talk to her tell her its ok you dont want to take her and that you understand her reasons (even if you dont) then tell her you have to go see someone and thank her pay the bar and leave..
Do this a few times and I promise you she will be asking you why you dont want to take her LOL
