Good for you for not sending the letter. I don't think it would matter. Time is what will make a difference. When you are selfish and care only of yourself no matter what is said, would the selfish one change. I think not. They don't care. Why should they, they got what they want.
It's only when the R ends or the op gets hurt will they step back and possibly think.
I understand about breaking ow glasses. I am glad I don't feel the anger like I used to. I just think ow was a fool to get involved with my h and now look at her sitch. How is that working for her now? It isn't. Guess the attraction wore off, it eventually does. It won't be all roses forever.
Time is your friend.
