Please be gentle, this is my first AIBU.
My brother lives abroad with his family (too far for us to be able to afford to visit). He comes back, with his OH and kids, to see family once a year.
He visits the family home, roughly 2 hours from us and from the airport (slightly different direction although we are half an hour from the airport). We are expected to drop everything for that weekend to see him there (he won't visit us despite having an open invitation).
He has booked his family's tickets for this year several months ago (I know this from conversations with other family members), but hasn't let me know when his visit will be. I know it will be during term time so we are limited to a weekend visit.
AIBU to expect him to let me know when he's coming over? I know the expectation is that I will join them at the family home but I can't keep every weekend free.
