The Rules of Engagement actor revealed to guest Robyn Lively on his Sibling Revelry podcast that he "spiralled" after he got engaged to the actress in 2004. "When I got engaged, something happened psychologically, and I spiralled, and I was unfaithful, and I was cheating, and I was crazy," he confessed, reports People. "I never got caught," he continued. "I told her everything because I couldn't live with myself and get married and be married and have children with this sort of weight."
