So, we're planning to include grandparents in our procession. My fiancé's paternal grandparents live on the other side of the country, but have both confirmed that they'll be attending the wedding. They've been divorced for many, many years and the grandfather is currently on his fifth marriage, and his new wife is attending as well. I should add that I've never met any of them, and my fiancé has only seen his grandparents a handful of times in his life (no one else who's attending has met wife #5).
Do we have any obligation to include his new "step-grandmother" in the wedding? If we didn't, would it be weird to have the divorced grandparents walk down the aisle together? Anyone been in a similar situation?? Without knowing any of them I wouldn't even begin to know how to ask them how they felt about it.
