BOY TROUBLE!!! TEN EASY POINTS!?

My best guy friend and I are very close. Last Friday, we talked on the phone for about a hour. He said he had to and would call me back at 8:00 p.m. He calls back mostly but sometimes he forgets (no problem). He never called back and on Monday he didn't speak to me (I didn't try to speak because he was acting weird). He ALWAYS speaks to me. Today is Wednesday and he still hasn't spoke. We locked eyes in homeroom for a minute but he still didn't speak. AND TO PUT THE ICING ON THE CAKE, I'm no longer on his messenger list! I don't know if it was on purpose or mistake but I'm totally buggin. Please help me!
