My sister and I are taking the kids to a pumpkin picking thing this weekend. Due to various things I don't get to spend much time with my nephews and it was meant to be a nice day out for all of us. I paid for the tickets for us four.
Sister mentioned it to her partner last night (who isn't the kid's bio dad!) and he's booked a ticket today and told her that he's coming. Never even asked if I minded.
I'm peeved because he always manages to spoil the day - he's quite grumpy/sullen and also expects coffee and stuff bought for him but never offers. It also means I'm going to have to unpack stuff I've got in my car so he can sit in the boot. I'm so annoyed I feel like cancelling the entire thing. I also don't know him very well and feel like I can't relax when he's around.
Aibu?
