Nadine had started betraying Billy before HB, before leaking Vanessa's name. Nadine handed (or told) Roger that Billy was secretly converting a warehouse (that was next to the Towers Spaulding was building) into a homeless shelter back in the Spring of '90. Then he wanted her to spy on Billy to see if he had the deed to the land the Towers was built on. But she always managed to slide by. Either it was deemed unimportant after the fact, or Van wouldn't be able to prove it, or her kids would cover for her. Frank even covers for her about leaking Vanessa's name, it's the reporter who told Billy.
Objectively, Nadine's insecurities aren't unfounded, but she always just goes that step too far. She handled the entire situation badly. First she accused Van of making it up to get Billy's attention, then she said she deserved it, which really cheesed Billy off. But yeah---Billy lost it when he found out she'd leaked Vanessa's name, and not only was he having divorce papers drawn up, he was telling Vanessa he wanted her back (which was the worst kept secret in town). If not for her sleeping with Fletcher, he'd have put a ring on it, (Which I find endearing as a Billy/Van fan.)
