My fiancé David seems to have an “I can fix him” mindset with his friend Sean. David is always making excuses of Sean’s toxic behavior towards him and stuff.

Sean clearly does not like him. Sean is always ranting and blowing up at David. He never wants to talk to David or hang out with him. He makes David really sad but David wants to keep his promise to always be Sean’s friend and thinks he can fix Sean or something.

I appreciate that David is trying not to talk to Sean anymore. I’ve just been worried about him that his friendship with him is one-sided and not the best, but I can’t control him and I don’t want to at all.

I just don’t know what to do. Kind suggestions, please?

Sean left a rant saying: (shortened, paraphrased) HOW DARE YOU JOIN THE MILITARY WITHOUT MY PERMISSION

I’M IN SO MUCH PAIN. I HAVE NO FRIENDS AND NO ONE TO TALK TO AND YOU HAVE FRIENDS AND A FIANCÉE AND YOU DONT LIKE ME OR EVER PAY ATTENTION TO ME AT ALL

I’VE TRIED SO HARD JUST TO BE YOUR FRIEND BUT YOU DON’T APPRECIATE ME ENOUGH. YOU’RE SO UNGRATEFUL OMG YOU SUCK.

YOU ALWAYS SAY YOUR LIFE SUCKS, YOU NEVER THINK ABOUT MINE?? IM MISERABLE!!!
