I talked to one of his friends and he (the friend) wanted to know what went wrong. it was difficult for me to come up with a solid reason. I told the ex a lie but I think he would have forgiven me because he was such a nice guy.
his friend reminded me of what type of guy he was, and I regret my actions. i'd like to talk with him even if it was just to apologize for how I treated him. i'd hate for him to let my actions make him bitter about women.
I unblocked his number hoping one day to get that random call from him

it hasn't happened.
