Whats up guys?

I've been lurking around these forums for quite some time and have found some great tips just by reading some of the posts here. This site has been helpful for my confidence especially after going through some rough times. Anyway, I think I'm going to start posting here more often. Now comes the question I have and hopefully some people can help me out here with a particular girl.

Sorry if this is long, but I'd rather give some details about this girl and my situation. I've known this girl for about 2 years now and we're in the same college and also work together (we only see each other about once or twice a week there). We talked and joked around quite a bit and even mentioned other guys and girls to each other. I knew she didn't want a relationship and just wanted to have fun for a while and I was totally down for that. So we started hanging out a bit and next thing you know we started seeing other each. This was around last fall/winter btw. We did fool around a bit, but only hooked up a couple times. It was after the second time that we had a talk and she basically said how she didn't want anything serious. This is were that inner wuss (the way I acted) in me came out as I ended up wanting more. Anyway, I wasn't happy with what she said so I walked away from it, while she surprisingly seemed more hurt. Aside from being civil, we didn't talk for a few months.

Now while she ended up enjoying her single life and met other guys, I ended up doing nothing and feeling bad for myself until one day last summer I just said fark this sh1t. I thought to myself, well if she's gonna have fun with other guys then I'm gonna have fun with other girls. That's exactly what I did. I'm single and I should be enjoying that life. So a few months after her, I felt great again and even met quite a few great women. The relationship with this particular girl was ruined because I became too needy and wanted to put a title on our relationship. I learned quite a bit from it and happy that things turned out the way they did. She is pretty much a girl version of me which is probably why I liked her lol.

Anyway, fast forward to a couple of months ago and we ended up talking a little more and even getting along better. We do have mutual friends (who all love me btw) and often times they'd even invite me out to events, where this girl would obviously be at. So one night a couple weeks ago it was me, this girl, and her friend having a drink after work. The 2 girls started talking about other guys (ex boyfriends, flings, etc) and then both mentioned how they are single. I knew were this was going and then the friend asked me if I have anyone in my life. I don't normally mention my dating life, but I basically said nothing serious (I am dating around a bit) and they both picked up on the fact I'm seeing some people. Naturally, they started asking questions and I just laughed and brushed them off. That was about 3 weeks ago and since then, this girl has asked me about 4 times now who this girl is (in a joking/curious way) and I asked her why she's so interested in knowing. She told me how it's because we are friends now. So I thought if we are friends than I'd treat her like one. I just told her how she's just a friend I hang out with sometimes and mentioned how I'm not looking for anything serious now. This was a party we were at btw, which was the same party I ended up getting a girls phone number that night. Anyway, we talked a bit more and then she mentioned some of the guys from the past she was seeing, but mentioned how she doesn't want anything serious either. We kind of had a heart to heart talk.

That was about 2 weeks ago and since then she's been talking to me a bit more and even started texting me a bit. A few days ago she even asked me to grab a drink after work. That night we did and a couple girls joined us. All I can say is that I had so much fun just just being myself. I had to leave early that night and she then sent me another text saying how we should grab a drink on the weekend. Heck, she even mentions future things that we should do sometimes lol.

Sorry for the long essay guys, but some input would be great here. I'm guessing she's interested again, but I've been keeping my distance and staying cool about things. I've also never showed any negative reactions when she has mentioned other guys. I wouldn't mind hooking up with her again, but I just don't want to come off as desperate. I'm not looking for a relationship this time around, at least not with her, but how do I go about getting her back in my bed without coming off as desperate?
