Ive lost my best friend?

I can understand you being upset over the fact he blocked and deleted you, however why can't he hang out with another girl if your just friends? Maybe just try talking to him, go to his house or phone him or something and just ask him-it could be over something stupid and small. However, it seems like you are quite controlling!! (no offence :L) but maybe you should just try to get over him.. or maybe he saw you as more than a friend, but you didnt catch on? If you want to be friends with him then talk to him, if you are not willing to do that, then get over him.
