Name changed for fear this is outing but equally hoping assuming this is a situation others have navigated and so can offer perspective.
DH, kids and me are the poor relations on my side of the family. Both sides of the family are split up and remarried. We are the only ones with DC. Every Christmas (and birthday for that matter) my side of the family make snide remarks that the presents we get them don't cost much money. This is because we don't have much money: we are a single income family (I was really unwell a few years ago and had to give up work, my DC are very, very high needs SEN and I care for them). We are forced to live in an extremely expensive part of the country for DH's work and the DC are expensive (think specialist everything needed from car harnesses to toothbrushes that cost twice as much). My DM is very wealthy, no mortgage, lots of investments, enormous house, very lavish holidays every year (non covid). My sister is well paid, single, ludicrously expensive hobbies, lived with my DM rent free for several years to build up very healthy house deposit, currently living in low cost house share.
This year my DM suggested doing secret Santa so that we all "actually get something we want". She proposed a limit of £50 per person and we'd all buy off a list of items we said we want. The DC are not included. I agreed initially without thinking about it. When I thought about it, I really don't think we can afford it - the people involved will be me, DH, my sister, DM, DM's partner so me and DH will be paying £100 while my higher earning sister will just have to pay £50. We will then have to do the same for DH's 2 families (parents split and remarried) and buy a present for my Dad, each other and obviously give our children a Christmas as well. With all of this we're looking at a £500 Christmas that we just can't afford. I guess me and DH could choose not to give each other presents or downsize the DCs Christmas to a very small one but that doesn't feel right to me?
AIBU to say no to this Secret Santa set up? How on Earth do I deal with the inevitable shit/fallout we will get from declining?
