A few years ago my husband organized and paid for dinner for a significant birthday I had as I didn't want a party. He invited my family and inlaws and a few close friends. Not one member of my family turned up but my inlaws and friends did, my dad had to work, my mum had the option to go but wouldn't get the bus over and my brother who drives didn't want to go on his own. I suggested my mum ask my brother for a lift but she didn't want to "bother him". Now my brother is celebrating a big birthday and my mum wants us all there for dinner to mark the occasion. I feel a bit hurt to be honest not that my mum is organizing a dinner for my brother but the fact that she's pushing for us to be there when they didn't go to my birthday. AIBU to not want to go or should I be the bigger person?
