I have this problem with some of my friends, especially with one who was my best friend including his roommate with me last year. He seems to ignore me, but will not say whats wrong. I have even went above and beyond sent a gift card to his house for his birthday, and I gave him one week later a call to see if he got it. He did not call back.
I will of course go ahead and make move with new friends, but this little bit hurts and I won't forget because with them it was like a brotherhood. I hanged out with those guys almost every Friday night or weekends. Now that new year began, they moved out, they got own apartment. I have tried to keep in touch via email, facebook, call. His roommate occasionally keeps in touch with me (and he had birthday 4 days earlier, sent him the same stuff and once he received he thanked me for that). Its very unlike that I will see him in person at school, once the winter break ends, because my school is very big. Any good idea on how to find out why my friend won't talk?
