What should i do about this girl ? Elaborated answers if possible :P?

[Saransh]

Well there is this girl in class who kinda shoots glances at me over her shoulder or turning back or just when facing me
She gives those Marilyn Monroe kinda looks
I look back sometimes and smile she smiles too
And we only spoke about 3 or 4 times that it
I had sent her a request in Facebook too but she didn't accept but I'm not the only one who's req wasn't accepted even a guy who is in her group isn't in her friends list ( she has a Facebook profile don't worrry)
But she gives me those baby face glances
I'm going crazy I don't know what to do she's very cute though
N sometimes of somebody in class cracks a joke and the students laugh that girl and me share glances and small smiles too
Help
Plus sometimes it i can see she's interested in me (feet pointing towards me shoulder glances ) and sometimes not and she has a boyfriend I'm not sure but I think she has one

Well if she has a boyfriend, don't be the one to ruin it. She could just be a flirty girl who thinks you're cute. but maybe sometimes after class go up to her and start some small talk. If y'all hit it off do it more often, not everyday though so keep her wondering when the next time y'all will talk is. stuff like that. if y'all don't hit it off, don't sweat it and keep with the flirtatious looks an such, as long as she is doing the same, and maybe one day something will happen with yall

There's really no elaboration to be done. Just sounds like both of you like each other...but both are too chicken to say something to one another lol. And that's typical. Especially in a school setting where you don't want to embarrass yourself in front of everyone. My advice. Send her a message on FB...who cares about whether she has accepted the friend request or not (perhaps she hasnt gotten online to check it yet).but Just send her a message and break the ice. Just hit her up and say "hey...im (so and so) from class... and im messaging you cuz you seem like a pretty cool chick, and i wanted to add you as a friend on FB..but you didn't accept it yet...so i just wanted to make sure you knew who i was and knew it was me from class instead of thinking i was some random creep" and just see what she responds.. Sometimes you just gotta go big or go home as they say. If you are afraid to do so because you are afraid of getting shunned, or having to go to class and feel awkward...then I have no advice for you in that case.

I used to be really shy at one time too and would never holler at a guy. And guys were the same way with me. So eventually I just started hollering at them or messaging them online and starting general talk or etc...and you would be surprised how much things can flow if you actual start the flow. So many people miss opportunities w/ other people..all because everyone is too afraid to talk and to try.
Now im currently settled down and have found a man who captured my heart. and we are now engaged. And when i first met him, i initiated it by asking if he would like to get my number and hit me up sometime? and it went from there. So see! Taking a stand and making a move doesn't always mean a bad outcome! And if you get a bad outcome...you will find a more pretty girl who catches your eye sooner than you know it.
good luck
