Have you asked them? What sort of friends cannot broach the subject with you?

There's no reason to continue living in that situation if you can make amends or discover that they judged you in a faulty manner.

Seconded. They probably can’t remember. It’s a powerful thing to hold over somebody. If they ever fancy a chick who’s fancying you at a party for example, with that type of person something is sure to come out to put yhem above you. I’ve had some shitty drinking buddies and cut them all out of my life. Good riddance.

Life is for fucking up and growing, which requires feedback.
