My wife and I are throwing the engagement party for her sister. We are trying to plan out the guests who will be coming and my MIL is INSISTING her 6 siblings are invited or she will not come.
The grooms mother is one of 12 or something so the bride tells me not to invite his aunts and uncles just his parents.
I feel we can't invite the aunts and uncles from the brides side but completely exclude the groom (except certain cousins who are in the wedding). I told them this but they don't care.
So I say fine, lets exclude brides aunts and uncles and of course MIL flips out. I feel like I am stuck between horrible etiquette by excluding half of the extended family vs. making my MIL angry.
Thoughts?
