In all honesty I'd rather not deal with petty arguments period. If something I could care less about then I'm not going to argue about it. If it something I feel strongly about then we may have to agree to disagree. And if it something that one of needs to change on our (core level) then it's possible we're with the wrong person.
I try not to dictate or boss my mate around because I hate it when someone trys to pull that stuff with me. It's very rare I have an argument with my spouse. And when we do it's not my goal to "win" so much as it is to have my side understood.
