Search Results: she is a sophomore and i am a senior

-Background Info (skip if you want):
So I have known this girl PB (super cute and sweet) for almost a year now, but never talked to her much in HS. She's INCREDIBLY shy & would actually get scared of anything. She would pull her arms in tight or twirl her ponytail hair whenever she got nervous. It was frickin' adorable.
Anyways, I didn't see her but once since the end of school last year. Fast forward through a summer and 4 months of college to today. I came back during her gym period to talk to her again. Now she is SUPER friendly & open to me, waving as I came in and asking all sorts of questions later. This is weird for her because she's usually super shy. We talked along w/ her friends. I climbed up on the bleachers siting right next to her, touching leg to leg & arm to body (breaking the touch barrier) & she was perfectly fine. I went to her lunch and sat next to her too and also leg touched, which she was comfortable with. I DIDN'T put my hand on her thigh though bc I don't want to go too far & make her uncomfortable. The lunch ended and I got up to leave for home. So I said bye to her & we hugged, except she hugged me SUPER tight. No female "friend" has been as aggressive with a hug like that before. So now I like her and she *should* like me.

-Problem:
I'm 18 & a freshman in college, she's 15 & a sophomore in HS. I'd obviously wait until her birthday in Feb. B4 I make a move (AOC is 16 in my state). So the age and life exp. gap is a problem, I found this out the hard way w/ my ex (15 & soph. me 17 & senior) how immaturity & expectations of teen girls can sabotage a relationship. I also have my own problems of hostility towards others (read my bio) that I need to work on as an adult. In addition, I plan on my next relationship being the last one (I like monogamy and marriage) but I know if I pursue it won't last more than 2 years. Lastly, college requires a lot of dedication & I'm supposed to date college girls. Should I try to date her or not?
