I've been reading your answers why do you think that two people who are in love will never fight? Isn't it human to have a disagreement an argument, in other words a fight? I think it is how easily and completely a couple can forgive each other & let go of the fight that is yarn stick by which to measure love. NO ONE NEVER FIGHTS!nI have been w. the same partner for 12yrs. I'm 32.
