989. Before starting school Arthur Weasley was sure he would fall in love with a Muggleborn student. He hated that his family was members of the Sacred Twenty Eight and the rest of his family wasn't too thrilled either. When he first met Molly Prewett they became fast friends, she too hated that her family was part of the Sacred Twenty Eight. In his fourth year he finally asked her out, realizing he never wanted to be with anyone else and she readily accepted.
