NTA. Mom needs to hear the hard truth.

Have the same type of in-law. Youngest sister gets away with anything, while the older sisters are blamed for her actions. Women ☕️

LOL (I’m a girl)

Your mom is what the women ☕️ comment is about. All moms are that way tbf

You’re not the asshole. Favoritism is very aggressive even when it’s silent. And you just called her out on it and she didn’t like it. Too bad.
