Ex lives 50miles away. Kids do not go to stay with him (their choice, they are nearly teens). We arranged for us to meet halfway where there is an activity that kids are interested in and he takes kids to do it. This is meant to help rebuild their relationship. At exs request, I am bringing kids earlier so we can go and all eat together at local cafe.
Activity is tomorrow, ex text this evening to say he is bringing his dog (which he shares with a friend and doesn't have full time) so I have to look after dog and we have to find a dog friendly cafe instead of planned place.
One of kids is autistic - last minute changes not good. I said no - he has to make other plans for dog because all is arranged and too late to change. Also it's not my dog and I don't want to be landed with a dog to look after for 2 odd hours in a town. AIBU?
