They call it the Seven Year Itch, but it had taken only four years of marriage for Teddy Lupin to get restless.
It had begun with the little things; he had know her since before he could remember, knew her almost better than she did herself, and her predictability bored him. He noticed for the first time how grating her laugh was, and her other quirks began to be irritating, rather than cute. He no longer desired her - he already knew every inch of her body. Her long Healer hours meant she was barely ever at home and awake, anyway.
So nice, kind, butter-wouldn't-melt Teddy Lupin embarked upon an affair with his wife's fresh-out-of-Hogwarts brother, the redheaded funny man who was just what he needed - different.
