She chose Regulus. Not him, Regulus. Similar in looks, in upbringing, in blood, in intelligence, but he was a follower and a budding Dark wizard. That was telling, wasn't it? She'd chosen two of the Darkest wizards currently in Hogwarts to consort with, so how could she be anything but a Dark witch? Maybe she wanted to make up for her blood status, to choose those who would hate her for it. Why associate those who would accept her if there was a challenge to be had? It made sense; he'd always seen ambition and competitiveness in her. Very Slytherin qualities to have, now that he thought about it.
