So this has been his pattern. He eventually finds any woman easy to forget. That should be a lot less damaging to your self-esteem than if it weren't his pattern. Not saying that it makes the loss of the marriage easy to accept.

Love is often blind alright, but I would find it hard to imagine that those ten years were all that full of bliss . . . not with a man who is essentially self-centered. Sooner, or later, he'll get his. He is not laying the groundwork to be surrounded by love in his golden years. Getting hurt, however, will not ever make him sympathetic to those whom he has hurt. That capacity is not in him.

I don't believe that you really "need to forgive and move on." You just need to move on. For the near future, you will not feel forgiving. It would be screwy, if you did.

On television, I see families of murder victims showing up at court to tell the murderer that they "forgive" him. That is such a bunch of crap. This idea that we are only as big as our capacity to forgive is something that I find highly questionable. Sorry to digress.
