Been together 8 years.
A had to go on a sudden emergency mission earlier this week to help their adult child, mental health crisis triggered by some appalling things happening. Had a physically exhausting and emotionally hard week. Drove home 5 hours today.
B stayed home (not their child), did great job of housework etc, went shopping today and planned to cook dinner for both. Then went to pub to collect menus needed for their big-number birthday party in 3 weeks as guests need to choose. Pub 10 minutes walk from home. Stayed for drinks and arrived home 1. 25 hours later than A.
A very upset B wasn't home when they arrived, as they feel B prioritised going out drinking over providing support, a hug and a cup of tea to A. B feels they were only an hour later and they needed to get the menus.
A called B selfish. B said A was overreacting.
Big row. A crying. B stomped off.
Who is being unreasonable?
A is unreasonable - YANBU
B is unreasonable - YABU.
