He was my only friend, a brother to me. Instead, he had many friends over. The friendship went awry because he cut his losses to be considered very demanding. I acknowledge that I poured on top and demanded the same. Then I asked forgiveness for my way and tried to save the friendship. But it was not possible. Since then he has treated me with cordial indifference and has annoyed a lot that I have felt sad and bad and has not been treated with kindness, I have been away for just the situation I do not do more damage. It's been 4 years and to give and take, as usual. My question is how I can treat to be colleagues, so my attitude is correct but at the same time it is clear that it really hurts not having you as a friend and that's why I can not be as friendly as he is with me ..
