"One thing I don't get and maybe this is just normal script, but she said " how could I want her after all she has done to me. I said forgiveness." ----
Though your answer is of course sincere, it is perhaps a little trite on its own. Perhaps you could expand if she asks you again... Really explain, extend compassion, make is about her...
"W, I know you have a good heart, you are a good person, a loving, caring, beautiful, decent person. To have made the choices you did, you had to be in incredible pain. I think I can understand how you got to that place, I think I even understand the part I played. I can be gentle, compassionate, and forgiving to the person you were in that painful place. Maybe you can be the same toward yourself. I try to be toward myself for the choices I made during our M that I wish I could change. No matter what happens, we are both going to have to forgive ourselves to have a good R with anyone. May as well try to forgive ourselves and each other at the same time. We've got a lot of love to build on, even if there is some work to do on the foundation."
