I have a friend/colleague who has helped me through a traumatic experience, however in that process I was unable to be a good friend/colleague to them. As a result, I have hurt them and they have hurt me as well. In trying to let the person know that "they do not realize how much they have hurt me", I feel that statement has made them shut me out. I feel the person has done a lot for me and probably doesn't understand how they could hurt me.
I feel I need to respect their feeling by giving them space and respecting things they have told me in the past to show that I am a different person and that was then. My question is "how do I rebuild this friendship if the person does not wish to communicate"?
If you want to stay friends with people it is unfortunately not the right thing to say: You do not realize how much you have hurt me, as that will definitely end the relation. Ask for forgiveness and send them a list of all the good things they have done to you. Hopefully that will help.
