One of those kids that hasn't had a real relationship

Hi I'm 18, and I have yet to have a real girlfriend. It's not the fact that I haven't know girls, it's the fact that I use to be addicted to just haning out with friends, and playing video games, mostly the video game part. That has changed recently when I met this girl at work, I swear she's changed what I thought about what kind of person I've wanted to be. I asked her out a month ago and she said yes, but we have yet to go out...my mom (who works with us) stupidly told her she would tell me employees coulnd't date...and she said she wanted to. But she always sends out these vibes, with the ways he looks at me, we make fun of each other a lot, and I just generally feel this connection. I even sent her this message on AIM about a week ago, telling her how I felt, and she said "your a turd" and "hehe", I couldn't respond because i was afk, but it seemed like a weird response (keep in my mind she's 19). Well this thursday we didn't talk about it at all and went on as our usual selves. The thing is because I think she doesn't like me, even though she said YES to going out and gave me a REAL number, I kind of gave up. I swear I try to be next to her, then I try to show I have no interest, but it doesn't work, I can't forget her...she just runs through my head. She's one of those girls that is always funny, and she's just someone I'd like to get to know, but she's never given me the chance. I feel like there could be something, but the weird part is we'll do all that stuff during work, then at the end of the day it's like nothing happened. One time when we were done with work she was on ehr phone, and I said bye to her and she was one foot away from me and didn't say a thing, and she even looked at me...kind of made me feel down. I even know her mom and dad because we work together, and they are just like her...cool. I don't know what to do anymore, because I feel so akward around her, we can talk sometimes, then others we just sit there. Keep in mind she's beautiful, and I'm meh, I've lost about 20 pounds in the last month so I look A LOT better, but still it seems like maybe I'm just not in her league.

I guess the hardest part of this is figuring out why she would say yes to going out with me and now it's a month later and nothing has yet to happen. I just wish I could figure it out, any help?
