<human>: Can you give me the gist of the text in a nutshell?

I took a summer class which lasted about a month and it just ended yesterday. I sat next to this girl which I got to know and we would talk to each other everyday. I think she was subtly flirting with me because she would do little things like sit extremely close to me, give me a hard time in a flirty way, subtly touch me, etc... 

Sadly, I didn't get her number but requested her on Facebook and she added me a couple days after. I was thinking of making small talk like what grade did you get for the class when they are posted, then taking the route of being straight up with her and say something like "I would like to get your number so I could take you out sometime," or something along those lines...
<bot>: I met a girl from class but don't want to screw up my chances because I have been terrible with women lately. Any advise???
