Very true !
And this doesn't mean that you become a yes man for your wife so she's always happy , no ! Also don't get so abusive with her -mentally or physically- that she's only happy when you're happy ..
It's a compromise , you guys will argue , maybe not today , not tomorrow , but at some point during your life together you will argue about something you two can't agree on , you will either convince her of your point or she will convince you of her point ..
I'm definitely not an expert on relationships but I find that to be the strongest point in my marriage , we are always trying to see from each other's point of view and in my opinion that's what makes a great marriage.
