If this person was gossiping to you, you allowed it. That's on you. Change the thing you can control: your own behavior.
Guilty as charged but when you've been friends since teen years, suddenly changing relationship dynamics once you grow up is difficult. It takes some time to learn that passively listening is as bad as actively gossiping. Also if you've been long distance for years, you don't have as much in common but your common college friends and its always hard to draw boundary when talking turns into gossiping.
