Create a list of the things that you don’t want your spouse to do if you ever got into an argument. “What are things you don’t want me to do or say during an argument?”
Accept those requests as ‘argument rules’ and promise to abide by those rules.

It is not about making your point, winning an argument, or being right; it’s about being right in the relationship with your spouse.
Always remember, whenever you break the rules, you’re essentially disregarding your spouse.
