I think he still has feelings for you but hes acting this way as a deffense mechanism because when you stopped talking for a long time he felt ignored and betrayed and probably decided that it would be less painful to stay away from you, he tried talking to you again but your over reaction (which i felt was normal) reminded him of how you have power to hurt him.Send him an email talking to him about this and assuring him that you would never hurt him on porpous im almost sure this would work.
