6 Months ago i asked DH is he wanted to be with family and friends for his birthday as he shares the same birthday with my MIL and i wanted to book a weekend away for the both of us as a suprise but i know that if i just went and booked it he would tell me that he has planned to spend it with his DM/family/friends.
He said that he thinks that a weekend away just me and him would be a great idea and a lovely suprise (We havent been away together just the two of us every since we met!)
So i went and booked a really expensive hotel, Theatre trip and a meal out the first night and a day out the second day (2 nights).
Well its MIL's 50th birthday and she rang him yesterday to tell him of the plans (On the dates that we were going to be away) that she was thinking/to ask if we can make it.
DH has come home and dropped this on me (He knew what dates i booked the weekend away as we talked about it for a couple of weeks/I was hinting ideas) He said that he cannot miss his DM's 50th so i would have to cancel everything so we could attend, I asked him if she is able to change the dates for the weekend before/after as nothing is booked yet and he said "No way, Don't be selfish".
She hasn't booked anything i have had this booked for 6 months and i asked him beforehand if these dates were okay because i knew MIL would kick up a fuss if i just booked it without talking about dates etc.
I have looked into changing the dates of our weekend but the hotel has no rooms avaliable.
So he said that i have to cancel everything i had booked as he wants to go to MIL's "Do".
It has cost me well over £1000 for everything.
This has REALLY upset me but he said "Its my DM's 50th so im going".
I asked him if he told her that i had a weekend planned for him and me for his birthday weekend and he just said "I forgot to".
AIBU to be VERY upset about this?
