My parents are going through an incredibly nasty divorce right now, and this week my dad told me that he was not planning on attending my wedding since my mom would be there. My wedding is still a few months away, but he seemed pretty serious; he is not helping financially in any way, didn't even ask what day the wedding was, he doesn't want to be involved at all.
Should I make my plans (seating arrangements, parent gifts, father-daughter dance, etc) as though he'll be there anyway, or would I just be wasting my time?
