What would you think if I told my best friend to stfu about his relationship?
I'd wonder why you lashed out at him for no reason.
Their relationship is filled with mind games. I don't like that he doesn't understand the games.
You need to do your part as a friend and listen to his problems because that's what friends are for. You shouldn't tell him to shut up if he really needs your advice, otherwise why bother having you as a friend?
Maybe I'm too involved with thier relationship.
I'm glad to hear you say that. It's good to listen to your friend's problems from the neutral zone.
