We found another drama worth sharing on the subreddit r/AmIthe*sshole.
OP, a 20-year-old new mom, had a baby shower at her mom's place. She wanted it to be a small family affair, so she made cute family shirts for everyone. Her brother's been with his girlfriend for 5 years, and they live out of state. Brother brought the girlfriend to the baby shower, but OP didn't make a special shirt for her since they're not married.
During the party, the girlfriend seemed uninterested, stayed on her phone, and left early with the brother. Later, the brother told OP's mom that the girlfriend felt excluded and upset. Now there's drama, and OP feels like the brother is mad. AITA?
