I just don't think that being unable to forgive someone is the most healing move. It can be, and I've had times in my life when I thought I would be better off without the drama that another person was bringing to me, but cutting someone out isn't always the answer. I know someone who cut her mother out and it didn't magically heal her. She's still haunted. It's not as if you can wipe clean all of your memories of having a mother, or wanting or needing one.
