Why did I suddenly get blocked from seeing his facebook profile?

[Christina V]

My ex got very angry with me a month ago, because of a lot of things I just can't explain. It's complicated, and sad. I would have really liked to work things out with him, but I couldn't because of circumstances. Anways, he told me he did not wish to speak with me at all, so I have left him alone completely. It has been a month. Anyways, apropos of nothing, I suddenly noticed that I am blocked from viewing his profile of facebook. I say suddenly, because I really care about him, so I do look him up from time to time, and I know. Also, I think he has been looking on my myspace page frequently, but I cannot be sure. Anyways. Why block me, suddenly? I am not even a friend. And he would have no way of knowing I was looking him up every now and again. It really hurts. All, apparently, because of one missed conversation at a crucial time. Why is he doing this? And why now, when we have no communication as it is? Is he trying to rub it in my face?
