Just read Greek's advice to another DB'er. I'm trying to live by this at the moment, BD...when I feel outraged at him for leaving me pregnant for OW and never wanting to give our M a second chance. I don't yet know how to LET GO with WH still in my life (and our child's life - cos he is only interested in her today) so I am limiting my contact with him where I can. It is too painful and I can't fully detach in that state. Anyway, for what it's worth:
"...you are suggesting that one grown up should be responsible for another grown up's feelings. Stand on your own. Feel what you feel and take responsibility for that alone.
Forgiving someone does not mean you put the offense "behind you". It means you take your hands off their throat for doing it. Whether you forgive him or not, you will have to deal with the hurt, the wound, the scar of what's been done. The forgiveness is as much a gift you give yourself as anyone else."
