<human>: Can you give me a shortened version of the text?

Today I spent some hours talking to college classmates. My college is very, very small, so the things I'll describe are feasible. The first (?) subject was "the genealogical tree of our college hook-ups" (hook-up ≠ sex). We found out it is perfectly possible to put everyone there in it, except me (for our classroom).

They didn't press for anything, but I felt they didn't know why did that happen. They don't know I've never even kissed a girl (even though that's arguably easy to be deduced). This happened because I've always thought I'd disgust people if I pursued them, as well as extreme risk-aversion. 

I ended up having a crush for most of my college years (I'm 2y into college) on a classmate and never pursuing anything. Never having flirted (partly because I'm clueless about doing this and I'm very afraid about making the other party uncomfortable) with her.

For months I tried to ignore her. It was terrible because she's part of my friend group, and it came out as douchy. I knew I needed to bring some type of closure to put this away, but I was too afraid to do so and I didn't see the slightest chance of success.

That changed today. I may succeed. It likely won't be humiliating if it goes wrong. Now, what should I do to pursue her? Asking her out right away is pretty much out of question because this isn't that much customary down there. **I need to flirt with her - how does that work?
<bot>: I have a long-going crush on a classmate. Thought it would be impossible to work it out, but it isn't. I don't know what should I do
