I have known this guy for approximately 2 years. We have been in an on amd off relationship since school. Now he is in a different city for college. We are in a long distance relationship now. Our conversation is reducing day by day. At present its nil. I contact him but he is unable to take my calls as he is busy. He is always busy these days. When he calls after a long time, i am unable to talk. We have been fighting due to this often. At times i think that he is ignoring me and has just kept me aside and only turns towards me when he needs me otherwise he does not care. Is this my anxiety? He is a very nice person. I don't want to lose him. What shall i do ?
