AITA. wife’s brother started college and she won’t stop talking about it. It’s very annoying to me.

Me (28) and wife (26) have been together for 7 years. My wife’s only brother started college and she won’t stop talking about him. Every conversation she shares something about him. It irritates me since I don’t think I she has ever talked about me like that. Her mom does the same thing. It’s annoying because her mom have only been talking good about the brother since I known them. Never help my wife out. It’s infuriating and now they both talk about the brother non stop.
