Why my friend is avoiding me?

This is karthi from chennai and i have completed my 12th standard. Actually, i had a friend named vijay, when i was studying 8th standard. We both were in the same class. We were very best friends. But in our school, they used to seperate the classes every year. So, we went to different classes. So, i was unable to have contact with him. During 11th and 12th standard , his character was a bit changed and he became a rowdy. So, even if i happened to meet him, i never spoke with him and he does the same in return. During this holidays, his father passed away in an accident. Then , i myself called him and convinced him and said him the reason why i dint speak with him for the past two years. He also accepted that and we spoke that day happily. Then next day was one of our friends birthday and we both decide to go to the birthday friend's house with a gift and we also enjoyed the day. Actually he want in hins car to the particular friend's house. We had a great day. At the afternoon, he took me to many shopping malls in his car and we were anjoying a lot. I felt he had much more affection on me. It was really true. It was on 22nd of this month. He said that he was going to his native to leave his parents there and he would return back to chennai the same day. On 25th evening he called me and said that he was going to his native with his family and asked me to join him. But the journey takes two days. So, i said , my parents wont let me da. He too accepted. When i called him the next day , he said, " please dont speak with me da, because im a bad boy, my character is not good, you must take care of your carrer, you must read well, you must succeed in your life, your career should not get spoiled because of me, dont waste your time speaking with me". I replied, "dont speak like a mental" and asked , when will u return back for which he replied, " I will return only after 3 months". But i love him very much. He is not attending my calls. I want him back again. He is not attending my call for the past two days and even today, I dont know , what to do? My heart is paining alot. Till this day, none of my friends except him , thought about my betterment. So, i dont want to miss him in my life. Iam crying a lot, i cannot do anything. I want him back again. What shall i do? We both were very happy and together only for one day , but i want him as my friend and want to be with him throught my life. Please suggest me something? Please Please Please.....
