I can't imagine my children meeting any of his skanky women. Thank goodness they are older and have told him that it is not happening.

The only silver lining I could possibly see is that everything that makes the affair more "real" makes it harder to stay in that ridiculous limerent state. Children are tired, cranky, complain, whine. I imagine seeing someone snap at your child or even replace their father might be difficult even for the person who brought all that into existence.

Try to keep some of that lovely hopefulness you came here with, but give it a good dose of reality.
