I am in love with my friend for six years. Several times he treated me badly. He left me and I was waiting and he was back.This time he had to leave to Europe for two years and he asked me what I was going to do and I said that I would wait for him. I asked him to write and he said he would write once a week. So he left and I was writing every day and he was writing once a week.

Then after half a year he was writing less and less and I was asking what happened, did he get another woman. So he sent me this email

Hi, this long distance is not going to work for two years. I don't want to
hurt you and I care about you so don't make this hard. I'll contact you if
whenever I am in the US. I am busy and you know I never write anyone much.
Hug

After that I cried a lot and kept asking "Did you get somebody, could you just tell me what happened" and he said that he worked a lot and that I shouldn't worry about him. What did he mean that I shouldn't worry about him, did he mean that he didn't have anybody? Is it a double talk? After that he never wrote to me again.

I kept writing every day and cried every day and yesterday I thought it was time to stop writing. How can I force myself to stop writing to him? I got used to write about my day etc, it was like talking to him, saying good night before I go to bed ..

If he doesn't want to be with me anymore, why did he say he would call when he's back? This is not fair to keep me waiting like that, just in case, to leave the door open..

Am I obsessed with him? This is not normal to love somebody for so long when somebody doesn't treat you very well.. How can I make myself to stop writing to him? Is there any method that would make me stop:

1. writing to him
2. thinking about him?

I cannot function normally anymore, I got physically sick and I cannot recover.
