I'm fully prepared to be told IABU so here goes.
It's my birthday in a few weeks and I planned to go out with friends for a meal and drinks. Exh works a job which involves shifts and he has one weekend off a month. He usually has DS midweek when he has days off. I asked which weekend he would be off so he could have DS and he told me, we agreed he would have DS that weekend. So I booked a table at a restaurant for me and a few friends.
He has now contacted me and said he cannot have DS as he is going to a friend's wedding. Normally I would not mind and see if I could change my plans but he has form for doing this. He did it before a couple of months ago when I was supposed to be going away and I ended up paying for a hotel that I didn't get to stay in. So I was a bit pissed off and said well it's tough because I've already sorted my own plans.
Honestly AIBU? If I am then I will try and rearrange but I'm a bit bloody fed up of always having to change my plans.
