likely she now knows that you are intersted in her, and she probobly now knows that you have an agenda to going out with her.
my advice is that you do NOT push this yet. You should have one more good interaction with her where you continue to build attraction. This will show her that you're not just trying to get her on a 'date' or something. and she'll be reminded that you are a desireable male.
then the next time you try to get her to come out with you. Say something like : " i heard of this great Laser tag place, and I'm going on saturday. you're welcome to come. My friend just called me and said she needs to talk about somethign important, so I'm unavailable until this afternoon, but call me after 3:00 and i'll tell you more about it
"if she ditches you or something....you mighta blew it. don't indicate interest for a while, and in fact, if she does blow this off, you could try taking someone else. Then if she asks you later that week how it was, instead of saying "oh i didn't end up going" (then she'll know you were just trying to get her to go with you) you would be able to say "it was great! Jonie and I went and....." this way you'll imply that you're not needy and if she's not availbe, then you're goign to have fun with other women.
that will indicate that you are a high value male, and she'll be much more likely to go with you next time.
hope that helps. good luck
