I truly feel for your pain. I am lucky enough to have my X and the OW live in another part of the state, so we don't 'bump' into each other. Your children are allowed to feel wht they feel, although I am sure he will blame you for their feelings, if the are not what he wants to hear.
As for the wedding, if he is unable to honor his D's request, ___k him. It is, after all, HER DAY. Although I expect, if he is like my ex, he will take exception and refuse to attend. HIS LOSS.
