This man is stubborn, He refuses admit he's wrong. He also refuses to apologise because why would he apologise if he's right?

That's a little harsh, he does end up apologising just with some intimacy instead.

You get in a stupid fight, something that was easily preventable but still ended up happening.

You're pissed off with him, giving him the silent treatment and not even bothering to sleep in the same bed as him that night. You sleep on the couch this time
