I'm not sure if this is 'love' but I need advice! Long Question..

So, on Saturday just gone I was out drinking from like 6PM til 5AM, with this group of people I've never actually been around before properly even though it was only down my local. However, a girl from my childhood was there from when I was about 12-13 and I had a crush on her big time back then and tried really hard to get with her, as much as you can when you're at such a young age. So after a few drinks, we got dancing, and then kissing, buying her a few drinks and all that and then I found out she hadn't long broke up with her boyfriend, now a mutual friend of ours tole me that "She hasn't been with him for like a month" But on her facebook they had only broke up a few hours before going out accordingly. So I mentioned it and she went with the month thing too, may be legit I'm not too sure. So I walked her home at about 5 in the morning and then was sat on her doorstep for about 30-40 minutes just talking and she said "I'm off to Turkey on Monday" Making conversation and I found out her ex is going too, and me being drunk said "You'll probably be back together when you come back then" And she said, "no. I doubt it, I don't think I want to." I also asked her would she consider going on a date with me too, prior to the new batman movie coming out.. We're both sort of nerdy people so I thought maybe it would be nice enough to do together.

Now these past 3 days I can't stop thinking about her and I also can't stop thinking am I just a rebound, from her ex, or was she being serious with me too? It felt nice when I was with her and I haven't felt like that with a girl in a long long time, I go out and get around some women sometimes and it's just a kiss to me but after me and her spoke all night it felt much nicer.

Do you think I should let this whole thing fly? Or see if she's still single when she gets back from Turkey and offer to take her out on a date?

And do you think I'm being silly for being so led on after something like this that has just passed? I'm feeling lost because maybe to her it was just a drunken thing, but to me it was such a great night haha.

Thank you, any more questions ask away and I will post in the details, thanks.
