It's better to agree anyway! Less stress lol. The gf makes me sleep outside the mosquito net whenever she's pissed at me (worse than the yelling and ignoring stuff, effin mosquitos)
25 years and seriously, the Wife and I have never had any large argument. Key is that she has been mainly in one Country and me in another most the time.
We have never had a serious argument, been over 7 years and we live together for most of that. I think the key is respect, knowing your role in the family, communication, plus we both have a very chilled attitude to life.
