Quarrel
The first time they argued they quickly made up. It was a stupid thing anyway. They were still happy with each other, so madly in love with each other. The second, third, fourth ties went much the same. But as time passed, the quarrels lasted longer, became crueler, not as easily forgiven, harboring resentment. As more time passed it seemed that the love had faded, both equally jaded. Fights, arguments were all they had. And finally they parted. No love held towards the other, they broke off the relationship now, both carrying a large portion of hurt and hate. Neither could remember why they had loved each other at all.
