I will start off saying that I can only budget for a small wedding. That is fine; FI has 18 immediate family.
FI's family has 2 uncles and one is married. One uncle has 3 "kids" (ages 28, 18, and 12) while the other has no kids and no spouse. So that's 7 "extended family" he wants to invite; they are very close so of course they would be invited. This is in addition to the "immediate family" so in total, 25 people.
As for me, I don't have any grandparents. I have two parents, two step parents, and a brother and sister in-law. I have 6 immediate family members I would invite. I feel like I should invite more family, but unfortunately, it's not as simple as FI's family...
I have 4 aunts and 2 uncles, all of which have spouses and kids. The total count is ridiculous--I have 7 cousins on my mom's side and 5 cousins on my dad's side. Two cousins on my mom's side are married, and one has 2 kids. My aunts on my dad's side are much older than my dad, so many of them are grandparents and have grandchildren more close in age to myself than my cousins are. I would not even know but it is possible the grandchildren my age might have children of their own. I am close-ish to two of my aunts, but don't really keep in touch with everyone else.
Assuming it's not appropriate only to invite select aunts and uncles, *and* assuming it's not appropriate to invite no aunts and uncles on my side when FI does---where do I draw the line? Just send invites to the aunts and uncles? If they ask to bring their kids (my cousins), that's fine?
To add to the issue, my brother just got married last year and invited *everyone* out (my brother and I both live in the Seattle area). All the aunts, all the cousins; everyone. Of course, only 3 aunts and 1 uncle (with spouse) came out, but as soon as I got engaged these four people reached out to me to send congratulations. I don't have the wallet to invite everyone under the sun, and quite honestly I am a lot closer to many of my friends than I am to most of my extended family.
Not sure how to swing this; would it really be impolite for me to just not invite any of my extended family? Like I said, don't have the funds so would like to keep it under 50 people. At the same time, don't want to make anyone cry. I know there are some people in my extended family who have an interest in going.
