The damage H is doing emotionally to us , is at a point now where it cannot be forgiven.
Someone around here has the quote... forgiveness is a gift you give yourself.
Eventually it will be beneficial for you to forgive. Time does heal all wounds.
But I do understand where you are coming from... I was with a W who came on without pretense, inserted herself as 'mommy' to my boys, and seemed like a dream come true in some ways. Of course now she is hateful, spiteful, vindictive, selfish, and has no care in the world how her actions affect me or the boys, or for that matter our daughter.
These times will pass however.
