My guy best friend just stopped talking to me and I have no idea why. The last conversation we had was when he was sick and I asked how he was doing and if he was better. I am away at school and its 2 and 1/2 hours away so I can't ask him face to face what's going on and he is ignoring all my messages- text or Facebook. I don't know what to do. He was in a relationship for 4 years and just got out of it this August and when we were in school together he would ignore me sometimes but that was because when he was dating his girlfriend she got really jealous of how we were. He always tells me I am perfect and beautiful and stuff like that. He also tells me he loves me like a sister, but I feel like if he did he would have been here for me when I was super stressed about school and other stuff. I don't know what's going on with him but I miss him because he meant so much to me. I don't understand what I did to make him not want to talk to me, in our last conversation he was really short with me. What did I do?

It could be that he had some other expectations from you while he was sick! Why is that his girlfriend was jealous of you? Is it because she saw some chemistry between the two of you? Also what is the reason of his break up with his girlfriend? It's not nice of him to ignore you, just because his girlfriend was jealous of you. One possibility could be that he blames you for his break up. But well m just guessing.
