In a new clip for the Lifetime reality show, "True Tori," the "Mystery Girls" star is hearing some harsh words about her husband Dean McDermott, who had a very public affair in 2013.
"Because this affair is so public, I guess I assume that everyone knows what's going on," the actress says. "So, when I hear my friends saying I'm not dealing with stuff, it's shocking to hear that and it puts it all into perspective."
Spelling reaches out to a close friend to get his take on her troubled relationship. "How forgiving are you in this situation?" he asks. "I don't know, we'll find out," Tori replies.
"You know that people can make mistakes, you could have made the same mistake. You made the same mistake in your first marriage," her friend explains.
"We were both married when we met. We both cheated ... and we fell in love," Spelling admits. "Well, it could happen again," the confidant warns.
The "Beverly Hills, 90210" alum hopes her marriage can be saved, but she knows it won't be easy.
"You don't stop loving someone because they do something really bad to you," she explained to Us Weekly. "He was my soul mate, but he completely broke my heart. It makes you not trust anything that's happened in your relationship. But until I figure it out, I don't want my kids to know any different."
She adds, "I owe this relationship more than just saying something horrible happened and dismissing it. I need to figure out if he can change."
"If I can't ever let my guard down again, then there can't be a relationship. I always said, 'If he ever cheated on me, I would be out of there!' Whether I can ever trust him again, that's the big question."
