DP’s family live in a lovely area of Cornwall. Every year his sister and BIL go to visit his parents and take their teenage children at Easter, we’ve been once or twice and we’ve only had Christmas with DP’s parents once.
We’ve been uninvited from family gatherings previously when SIL and BIL have all been invited to stay, and despite us having far less money, once or twice we’ve stayed in hotels nearby with our DS, 3 and DD, 7.
DP asked his DF at Christmas if we could visit them for Easter; neither of us have much holiday due to childcare. They said yes, they would love to have us; his DF and younger sister mentioned how we’d not stayed for a while for ages and hadn’t been at Easter for years. Our DC are wildly excited.
FIL sent an email recently to all confirming we were visiting at Easter and did any of the other family want to come another time.
Older SIL has been really rude in response and says her family - who spent Christmas with MIL and FIL - had booked to go there at Easter six months ago. SIL and BIL said their kids would be absolutely devastated not to go, it ruined all their holiday plans etc etc. They have multiple holidays every year, to v v pricey destinations.
DP stood ground and said we’d asked to go ages ago, asked SIL why she thought it was ok to be rude via email, and said that our DC would also be really upset not to go. They’re only little, there’s absolutely loads for them to do in the area - we will drive from London so obviously want to go for a decent length of time as journey is so long.
SIL and BIL went quiet. But today they have messaged to say they’re still going, and that we can go but only for half the time we’d planned. MIL has asked if we’re ok with that, but we’re not. There’s kind of no point going for two days. AIBU just to cancel? Does it just look petty? I’ve kept out of it but I’m fed up now - we’ve had a really difficult time lately and really wanted a break!
