Love is not a victory march sang a wise man once. It used to sound depressing that love was a battlefield, a sickness, a disease. but love is not always good days holding hands, cooking dinner together, picking out furniture. love is not always no-you-go-first's or i-love-you-more's it's not always sacrifice and silent support it is long days, disappointment, and let down much of the time.
But what it means is that on those bad days, those battlefield, let-down days that you aren't alone that they might cook you dinner and encourage you to follow your goals and that you get to fight over doing the dishes. It means that someone is trying trying to hold your hand and hold their head high in a victory march and shout, whisper, tell you Hallelujah. God be praised, we have each other.
