About 3 weeks ago my MIL said she would like to arrange a family lunch before Christmas with us, her DD & family and her sister & nieces as we won't be spending Christmas together. We said we thought it was a great idea and mil suggested going for a meal somewhere near to where they live which is about 50 min drive from us. We agreed on a date.
About a week ago mil tells dh that she had a text from one of dh cousins suggesting we all go round there for lunch in their new home. Mil agreed to this but said she hadn't read the message properly
. This cousin lives at least a 2 hour drive away from us & we have a 6 month old baby. Dh & I agreed that we don't want to spend at least 4 hours in the car in one day with the baby & would rather go somewhere that's relatively convenient for everyone. Dh explained this to mil but she seems reluctant to explain this to the cousin because she already 'accidentally' agreed to it, even though Dh said that we wouldn't go if it's at the cousins house. I'm very annoyed as we were the first ones to agree to this lunch & were looking forward to it and now we are the ones not going because mil thinks it can't be changed. I appreciate that we could do the drive if we really had to but driving for 4 hours wasn't part of the original plan. Aibu to expect mil to rearrange the location so that we can also go even if it means annoying the cousin a bit?
