We can't make them be who we thought they were any more than they can do that for us. Bill is not lovely and warm or even particularly kind. You, my dear Katie, are one of a kind, a real gem.
Don't let him bring you down. I would keep any contact to the absolute minimum. You can't make him be a good Dad. What happens there is between himself and his children. You are their Mom. The strong rock they can count on. Keep that focus and you will be fine.
hugs, kat
