What is up with this girl? please answer?

ok i was cool with this girl as "friends" last year, we went to the same college but now im 80 miles away at another school. So we were always cool with one another, often writing on each others wall on facebook. One day tho, i accidently offended her by joking around saying " i cant stand your cheap leopard azz". i didnt mean anything by it,i was just joking like i always did. I actually think she has nice taste in clothes. But shortly after that, i realized i was blocked from seeing her facebook wall. So i apologized saying if i offended you in anyway, i am sorry, thought i was just having fun. All of this took place a week before halloween. she never replied back, so then about a few days later i sent her text, and said that i was commenting her too much on facebook, which i thought was a total cover up, just so she wouldnt admit that she was hurt by my comment. I went along with it tho and said i will back off. So then about 2 weeks later i noticed that i was deleted as a friend. I left it alone for a few weeks, and then on thanksgiving day i tried to add her back, i sent her a message saying again that i was sorry for poking fun at her clothes, i was only joking around and that i didnt mean it at all, can we start over? well 2 days went ped and she ignored me, she left the request pending. I could see she was talking to our other friends so i know she saw my request. i got upset and deleted the friend request and automatically blocked her. I had her blocked for about 3 weeks, then i unblocked her cuz i thought i didnt want to be petty anymore. i saw her talking to our friends on facebook, and we would both comment on someones status at the same time, but not talking to each other tho. But then i realized that she blocked me now and i cant type her name anymore in the search. Why is she being like this? i dont understand, im a guy btw.
