I'm pretty sure everyone who replied to you is male (I may be mistaken)... so take it from a female:
You are out dude and she is trying to not be bi...uh witchy about it. That isn't to say that you cant recover from the disaster of your first date though.
First dates are a real make or break. I almost didn't give my husband a second date because he wore really ugly shoes on the first date...
I know that's low and shallow sounding but its the truth. My friend had to talk me into another date, which went way better (obviously).
So, if you can, get a friend to talk you up, maybe a second date will be better. But don't hang out in the friend zone.... if you do, you won't get out of it. If you can't get a second date, just walk away and act cool. It may make her crazy enough to ask you out. And if it doesn't, go find another fish.
