girl i like wont accept my friend request?

[Black]

so i had this girl at my university class which i really liked, we did not really talk or anything ,sometimes when she would walk towards of me she should would stare at me.......... when i used to tell some jokes on our group she always laughed....never really had a chance to stop her for a light conversation(i was planning though)...anyway about 2-3 weeks later i changed university..... (it happened during winterbreak as a suprise)...and i realised now that i wont have the chance to talk to her.....so i decided i would search her on facebook...she had deactiveated her facebook acoount(according to my friends).................and i thought well thats it....until 2-3 months later i search her on facebook, she had opened a new account that day(it was a fresh new account, not the old one),i did not add her right away i waited about 2-3 weeks...and then i added her...(and yes she does know my name im like 100% sure of it,one time i heard her friends talking about me saying that i have a hot/ripped body,(just wanted to add that detail, i dont want to brag about my self or anythin, and yes i do work out, i take it very seriosly).....and when i added her she still has not accepeted my friend request(been 3-4 days)....what does that mean seriosly..im so pissed off.....i mean she could have added me, then when i would chat her, she would have shown me that shes not interested, or something,i dont mind getting rejected at all( just dont want to make a fool out of my self)....im just so pissed off....what should i do?
