Tomorrow is Mother's Day (here in the US, I understand you have yours on a different date in the UK). DH's advisor from grad school is in town, and DH wants to arrange to meet up with him. AIBU to let this bother me a bit?
I don't expect DH to do much for me- I'd be quite happy if he did the cooking, got me a small present & some chocolates, and watched the kids for a while so I could have some time for myself. I don't think that last one will happen if we meet up with his advisor.
OTOH, his advisor lives a long distance away, and doesn't come to our city very often. DH does go to the city where his advisor lives reasonably often for work, but his advisor doesn't get to see our DCs on those visits, since they and I usually don't go.
AIBU to not want to get together with him tomorrow?
