Affiliate Marketing Secrets

Hey guys, questions like this may have been asked but this one is slightly different (sorry for length).
Im in university in Canada in third year now and during first year in residence there was this girl on my floor who I thought was quite awesome (high grades, scholarships, social, attractiveness etc…) but never really got to know her too well. We did chat in person now and then and on facebook exchanging birthday wishes (I usually start the convo.) and such over second year summer and the summer just now, although we did lose real contact for much that time.
She’s now is in our schools affiliated business school’s reputed program where I plan on applying this year. About a month ago, I saw her at the school rec. center but didn’t meet her and fb msg’d after saying I saw you there, how are things etc.. and she replied well and I talked to her about her summer jobs and stuff she did (that she posted on fb) and sent another message saying I wasn’t being creepy and she replied no worries and thought I said we should meet up with all other floor mates as well. I finally said that we never got to know each other and we’ll hopefully bump into each other and good luck with your year and ended the convo. (these were private fb messages, not wall posts).
She does have many friends and is social on fb (about 800?) and reallife. About two weeks ago she posted her twitter account link on fb and asked people to follow her to which I did reply ‘lol twitter(i think)’. I remembered and saw that post yesterday again and used my old twitter account (that I never used and coincidentally for the timing) and followed her (she had many about 100 followers) and tweeted to her that its my first follow on twitter and hope to learn how it works and expand my network esp with the students at the business program which I really meant and intend to do.
Next day (now two days ago), she blocked me on twitter and facebook (same username on both accounts). I think I creeped her out now and I really never meant to and want to apologize. But aside, one thing is that I myself am determined and hardworking and ambitious (if she remembers my grades from first year) like she seems to be but I’m not too popular.
Now, I have her mobile number from a while back from her fb post before the block which I think is still her recent one and don’t know if and how to text her. Or should I make another twitter account and apologize, but everyone will be able to see it. Or should I make another fb account and private message her (obviously letting her know its me).
Which is proper and how should I go about apologizing and when should I apologize (been two days now) and ask her if its ok to renetwork simply for connections, as I really want to get to know her ?
Thanks guys, sorry for the repost, really waiting for some good suggestions.
