When me and my fiancé finally set a date (September 3, 2022) we asked our parents if there was anyone they'd like to invite to the wedding. My parents struggled to give a list of 10 people (four being my great aunts/uncles). My In-laws gave me a list of almost 20 people (some great aunts/uncles, others just friends) and they kept adding to their list, it's now at 32! (I don't even know all these people) My MIL just told my fiancé that she wants to invite another FIFTEEN people!
I'll add that we live in Alberta, Canada and have are travelling home to Newfoundland, Canada for our wedding and have two small kids. (flights will be at least $3000) How do I respectfully tell them that we can't invite all 32 let alone the extra 15?! They are paying for our DJ (he's a friend of my FIL) and said that they will pay for the extra 15 people but won't help pay for the original 32 people.
