First thing to do: STOP TALKING ABOUT THE RELATIONSHIP!!!!
There is no other starting place.
Second thing: STOP FIGHTING WITH HIM ABOUT EVERYTHING AND ANYTHING. This is an absolute must. You are NOT going to argue him into seeing things your way, you just aren't.

Things to think about: Your H is more likely to be swayed dand influenced by a total stranger right now vs. you. So stop. Stop trying to change him.

YOU change first. YOU.YOU.YOU.YOU.YOU.YOU.
You can change you. YOU CAN NOT CHANGE HIM. So why bother?

Stop the fighting. Stop getting worked up over crap he does and says. Ignore it. Start the change in you there. PROMISE you, there will be not one fight this weekend. Then Sunday night, promise yourself, not one fight until Wednesday and so forth....unless he punches you or someone else....let it all go. Just try it. See where it takes you.
