So here is the long story shortened...
We asked my fiance's mom for addresses for some people on her side of the family which she gave us. That turned into a discussion about guest list in general and she's like we have to add this person. My fiance asked who that was and she said its the principal at the school she works at. She wants to add her co-workers all of a sudden and it doesnt sit right with me because she blind sided us with it and didnt even ask if she could. She just said she gets to because its her sons wedding (which yes it is her son's wedding). It doesnt sit well with me though because my parents are paying for the entire reception as well as anything thats been bought or booked for the wedding so far and we have a tight budget to stick to which she is more than well aware of. Plus my parents will probably end up paying for 100% of the wedding just because of the vast financial differences between the 2 families.
How do I handle this because honestly the guest list does not allow for anyone to be added to it since we have pretty much reached our max?
