As RadarOnline.com has learned, Eustace came clean about her relationship with the actor, telling DailyMailTV that he cheated on her with Spelling, then married her, had five kids and now regrets his actions.
McDermott was married to Eustace from 1993 to 2006 – when he allegedly had an affair with Spelling. The duo divorced that year, and weeks later the star tied the knot with his current wife.
"A year and a half ago, Dean confessed to me that he had made a mistake and he wondered what his life would be like if he had he stayed with me. He said, 'Do I love Tori? Yeah. But I've thrown my life away,'" Eustace claimed. "It was the most bizarre conversation ever. It made me feel irritated. I don't want any more drama. It was crazy, extreme behavior."
She went on to say that she has been more than fair with her ex over the years, even trying to build a friendship with Spelling despite the drama between them, for the sake of her and McDermott's child.Eustace explained that her son, Jack, 19, has suffered greatly from her divorce from McDermott and from his relationship with Spelling.
Amid McDermott and Spelling's financial woes, "Jack had his bank account cleaned out twice by debt collectors," Eustace claimed.
The single mother was recently forced to go to court because McDermott's child support payments had stopped. "I want to be clear," she said. "I signed off on three years of child support that my ex-husband did not have to pay. I cut him a break on that and covered everything."
She said that she let the money issue go before, but after it happened again, she had to put an end to it.
"When it stopped again, I said, 'it's not even about the money anymore, it's just about being respectful to my son and my family.' I wasn't going to participate in a circus anymore, so I just took it into my own hands."
Eustace added that McDermott's financial problems and strange behavior are not like him, or at least not like the man she once loved.
"The man I married is not the same guy he is today. We had our challenges, but there was no indication of this type of behavior. He appears different. I've had contact with him over the past while and I don't buy any of it anymore," she said. "My feeling is that Tori controls everything and she runs the show. Dean has no say in anything."
