I am a widow with a son and a daughter who both live a few minutes away from me. My daughter can't have children and my son has a daughter from his previous marriage. He now lives with his fiance who has two adult children from her marriage.
It's my granddaughter's birthday in a few days but due to her mum having made plans for the day, they're taking her out for a meal tomorrow, night along with his girlfriend's children and her daughter's boyfriend but I'm not invited. I'm really upset but he doesn't care. AIBU?
