My friends are coming from Singapore where they've been living for 2 years and will be going round staying with lots of friends and catching up. We agreed 2 months ago what dates they were coming to us and they've planned themselves a tight schedule.
2 weeks ago MIL phoned and asked if she could come to stay for a few days which I said was fine. We discussed dates and initially she wanted to come while friends where here which I said was not convenient as we only have one spare room so we agreed she could come the night after they left. Everything sorted or so I thought.
This morning she phoned to tell me she has now booked her train ticket, made arrangements to invite her friends to dinner at our house (which I'll be cooking!!!) and is coming on the same night as my friends.
When I pointed this out to her she said she must have got confused and they'd need to stay in a hotel as she's booked her ticket now. When I told her that wasn't possible and she'd need to change her plans back to what we'd originally agreed. Now she's phoned DP and told him I've insulted her and she wants him to sort everything out as she "is coming regardless of anything thefuture may say as she's family so more important"
AIBU to refuse to change my plans and tell MIL she can stay in a hotel?
