Hello everyone,
First post here, so please be kind

Looking for other perspectives on my situation...
My fiance and I are planning a very small wedding, at a very small woodsy location, in early September. Our guest list has been minimized to the bare minimum (40) and we are technically 10 people over our original limit at that number. My mom, however, is being very pushy in trying to get "only 12" more people invited. When you're already at 10 over the original limit, 12 more is a LOT!
Granted, I haven't invited a lot of people from my family - just parents, grandparents and my brother. Everyone else on the guest list is my fiance's family, and very close mutual friends. I come from a large family, so to invite one aunt/uncle pair, means you have to invite them ALL - or someone gets offended. Add to that all cousins and their kids (again, invite one and invite them all), and we have an additional 75 people on our hands at a minimum.
We wanted a really small, fun wedding - and I don't feel it's necessary to go crazy with my half of the guest list since it's my second wedding. I'm also not going to change the guest list - all the save the dates have been out for a while now.
Not looking to change anything - just looking for opinions and advice (and to vent!). Anyone else have a similar situation or ideas on how to handle this without blowing up?
Thanks
