Am I too young for her? 10 Points for best answer?

So last Saturday, me and my friend went out clubbing. We had lined up to meet a whole bunch of people there. We showed up and said hi to everyone, hugged them all. One of our friends brought her girlfriend, lets say her name is Cindy. I introduced myself, gave her a hug, she asked me to dance. All night we were dancing, kissing, everything short of f*cking basically...It's a nightclub there's only so much you can do. At the end of the night me and Cindy were sitting outside on the sidewalk and talking, and she was saying things like she saw her high school teacher its been so long, and she is 3rd year uni student. I am straight out of high school, 18 years old, she's 22.

She asked how old I was, I told her 18 then she was like "Oh no...That's not good, ugh why did I do that?" And I was kinda like wtf...I don't personally care about the age difference, all the girls my age are immature. Do you think I stand any chance, even just friends? Or did we push the bounds too much?

PS: She's smokin hot, if that makes any difference
