SA, I'm glad to see that you've made your plans. I think you are very wise in giving him an option, if he should be so kind as to grace the presence of you and your daughter.
I think it's just awful the way he behaved. This is a very special time for your daughter and one that should be shared w/both parents. Oh, well...his loss and one that he will never be able to recover.
Enjoy your day!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
