Why did she hate me for no reason?

[El Guero De Pachuca]

I first met this girl in mid 2007, she was in the 7th grade and i was in 8th. i didnt notice her much at first or know her at all not even her name!
at first i kinda lead her on by checking out her rack, whistled at her, and told my friend who was in her class to tell her that I thought she had a nice butt. he did and and thats when she started stalking me, glancing at me, sitting close to my table at lunch and giggling with her friends, her friends would push her towards me, she said to my friend she wouldnt mind me marrying her. :o
So I told my friend to keep an eye on her for my safety and he discovered she was writing poems and hearts and stories about us. I so was grossed out because of how ugly and pimply she was, so i started calling her names like cow, uglya$$, ms. piggy, b.e.t.c.h. etc. and make out with my crush after school in front of her and she would cry but she never got the hint. after that year i never saw her again until yesterday when i came across her facebook started looking thru her pictures and she looked cute. I accidentally liked a picture of her puppy then unliked it and logged off. A few hours later i tried to looked at her profile but turns out she blocked me. But im wondering why she blocked me for no reason? why would she do something so dramatic like that? I know it shouldnt bother me but im really curious. does she hate me?
