Why did she block me?

[Maddie]

Ok so we used to be friends but then something happened and we argued on facebook then she blocked me for awhile. Ok i know im a stalker but after 7 months i could see her on fb which means she unblocked me. So later on after that i sent her a request just to see what she does & to my surprise she accepted it. Well 4 months later i saw her recent status about one of my brothers so i commented on it asking how she knew my brother. And i tried going to her profile and thats how i found out she blocked me. My question is why? We never talked on fb the 2nd time we were friends.
