For background context, DH, DS and I are living with my parents due to an issue with our previous house, we'll be staying here until we're able to sort out our housing issues.
My parents have been abroad, and returned late yesterday, I intended on spending the day with them, as they've been away and wanting to see my DS. They were also very excited to prepare my favourite meal- as they brought back things to prepare dinner for us, knowing how much I adore the dinner they planned. They had to pay at the airport extra luggage, as they made sure to bring back our favourite things to prepare for us and were super excited to make these things.
However, MIL and my DH had apparently decided, without consulting me, that we would be having dinner at my in laws tonight. My DP said it was no issue and they could prepare dinner another day. It's not a problem with them, thankfully.
I think this is all a tad unfair nonetheless, because usually we see my in laws once or twice a week (not more because of DH's work) have always told them they're welcome anytime to come see their DGS. Due to my DP being away we have seen them five/six times in the past week, as we tried to make up for the fact that we don't always see much of them. I was more than happy to spend more time with them and invited them over for dinner a couple nights as they invited us.
We usually spend saturday nights with them, but DH and I have a birthday party of DHs friend so won't be able to make it to dinner at my in laws. Thus MIL and DH arranged for tonight as "it's not fair that we won't be attending saturday" but I think it's really unfair that I won't be having dinner and having a proper sit down evening with my parents until Sunday, when I've seen them so many times this week!
What really irritated me was them arranging things without consulting me and just telling me of the plans after they were made.
I have spoken to DH and told him i don't believe this has been fair, and he suggested we cancel tonight, understanding my frustration. MIL has previously complained we're keeping her at arms distance and shutting her off from seeing her DGS because we once had to reschedule dinner with her. I told my DH it is fine and we can go tonight- as already spoken to my parents too.
But, AIBU to be annoyed, I was considering have a word with my MIL because don't think she's being fair- but also, wanted external opinions since I do live with my parents and don't want to cause an argument, especially if i'm in the wrong.
I do understand we live with my parents so see them a lot more- I don't want to be unreasonable and come across like I only care for my family, but I don't think it was correct of her to not settle for another day and insist we must see her tonight when we have spent so much time with her in the previous week.
