That's the key - commitment through thick or thin. Love means self-sacrifice and the desire to please the other, not seeking one's own desires.
I think a balance....it’s never 50/50....nor was marriage designed for that. Sometimes it isn’t any % for a time as the marriage itself carries you because you’re both committed to the marriage....especially when you might not like each other for spell.
Love means a whole lot of things now days.....I don’t like to broad brush everything with love...it’s true meaning has been lost in this country.
