Sobriety experts said Joe Manganiello's sobriety may have played a major role in the breakdown of his marriage from Sofia Vergara. A source close to the couple detailed the significant impact that their different lifestyles had on their relationship. One insider told DailyMail that Joe - who has been sober for 21 years and has been candid about his past struggles with alcohol addiction - was warned about getting into a serious relationship with someone who was not actively sober. “Of course the fact that Sofia is not sober had an impact on their marriage,” the source said. “He was warned about this when he started dating her and again before marrying her. He did not think that he was going to change her but he also didn’t think about the implications this could have on their marriage.”
