Married lesbian here, that achievement is impossible. Arguments aren't won, we just both keep repeating our points until we're almost shouting, then lower it down to aggressive stage whisper so the neighbours don't hear us, before finally concluding our arguments with repeated 'FINE's before deflecting to something else - starting dinner or laundry or taking the dog out - that 'needs to be done' and then ignoring the other person/topic of the argument for about an hour until one person brings up an unrelated topic and we both repressively pretend the argument never happened and continue the rest of our day in happiness until the argument eventually bubbles back up to the surface.

The closest to 'winning' is when one of us realises the other is right or has a point and makes an effort to change, but only after the arguments run through the mentioned course and it's never brought up that effort/change is being made because you don't want to admit the other person was right.

We only have like two-three of them a year but they're intense. The rest of the time our arguments are usually 'I love you and understand how you feel and acknowledge your emotional response and how it relates to your upbringing, but these are my opinions on the subject and I feel we should look at it from this perspective a little more'
