Was I right in asking for forgiveness when most would say I shouldn't have?

I fell in love with a man who lied to me, took advantage of me for my money. I could keep going but this is not the point. He moved very far away. He is an angry man but I know in his heart that he really cared for me but unfortunately he doesn't know how to love back without hurting someone. This was 7 months ago and I was angry, hurt because of all that I did for him and this was how he paid me back by firing off an email saying I was "mean-spirited." I can't let go of these feelings of betrayal. I saw a speaker yesterday that stated that a person in order to get past this hurt is forgive and if all possible ask that person for forgiveness of any past wrongs. Since I have not been able to get over this hurt and bitterness, I emailed him and told him I was sorry for any pain I caused him and told him how important it was that he have a peaceful life. Why can't I get over the fact that I was wrong in doing this? Anyone out there who can help me tell me I did the right thing?
