Reporter: Brice stimon is now serving a seven-year sentence after he terrorized soraida, posting fake profiles of her on escort websites and worse, posting a sex tape of the two of them. To this day, she says she has no idea how he recorded them. She never saw a camera or a phone to capture them. I have no idea he had ever taken this. And he forwarded this to over 3,000 people. Reporter: And this was video of the two of you -- of me and him having sex, yes. Reporter: And that video spread faster than she could have imagined. Multiple porn sites. But what was worse was the family and the friends who authorities say were sent links to it by the manss soraida met on that plane. Could you believe this was happening to you? No, I didn't believe. I kind of, like, put it in my head that it was just a nightmare, that it was not true. Reporter: But it was. But it was. Reporter: And there was that one last surprise for soraida. Apparently he was married. Reporter: You have met the wife? No. Reporter: Nor had we, until just this week when "20/20" sat down with bruce stimon's wife of 22 years, mrs. Kathleen simon. He had been weaving a web of lies and deceit with me for many, many months. That's what hurt the most. Reporter: She and her husband have a 13-year-old son. She's a school librarian, now a single mom raising that son all alone, back in their small new hampshire town. Authorities have been watching her husband across two states and she is talking about the case now because she says no one has paid any attention to the terror he inflicted on his own family. I think throughout this whole thing, it really has never been apparent that bruce had a family. There was never any indication that he was a married man with a child. We're victims, too. Reporter: Kathleen says during those months, she had no idea what her husband bruce was doing on those business trips to washington, d.C. His time spent in arlington, virginia. Nor did she know what was about to unfold on that fateful night that authorities were waiting for him. Bruce didn't come home. He said he was going on an appointment in massachusetts and that he might stop at his mother's house. Reporter: He left that night in his cared all would drive more than eight hours, all the way from new hampshire to soraida's apartment outside washington. As the case unfolded, his long-time wife was horrified. The things he did to her took hours and hours of plotting and planning and very devious, very ugly and when you involve somebody's child, I mean -- it's the lowest thing you can do. It's just despikable. Reporter: After learning of her husband's arrest and betrayal, kathleen demanded a divorce. And that's when he began using some of the same tricks to orize her, too. He shut off the utilities going into our house. He took over facebook, ebay, paypal. I thought I was safe because he was in prison. I didn't think he could be capable of doing anything during that time. Reporter: And she would soon be left with yet another unwanted surprise. 50,000 in bills for all of those trips and all of those gifts left at soraida's front door. The flowers, the chocolates, the lingerie. And when she realized that, even her friends were asking this. When was the last time you spend $50,000 on you? I just can't imagine. I don't know what would be going through his mind to spend that kind of money. She was a virtual stranger. Reporter: A stranger who fell for him on that flight. I think he appeared to have money, pretended to have money and she went for it and she found crazy. Reporter: She found crazy. And it's still haunting her tonight. Are you still afraid? I think that I'm afraid that he's going to pay someone to kill me. Reporter: Tonight, that sex tape can still be found online. Authorities say once a video like that is posted in multiple places, it can be nearly impossible to take down. It can ruin a person's reputation and it's very difficult to get that information back. He was using the technology to destroy a person's life. Reporter: He was destroying your life? He did. Reporter: And soraida's daughter pam knows that awful tape of her mother is still out there. The video was my mom, so, everyone was convinced that it was my mom. Reporter: What he has done to your life? He -- he destroyed part of me. I will never see men the same. Reporter: A daughter, now watching her mother trying to rebuild their lives. When you see her fighting this, what do you think? You just can't give up. My mom didn't give up and I'm so proud of her and I love her so much. Reporter: And when her mother who had been listening to the interview heard that -- that nightmare, finally over. I love you, mom. Reporter: All of it, after that very first flight when it seemed love was in the air. Will you ever look at people on the plane the same way again? I will never give them my number again, that's for sure. I learned my lesson. Reporter: It all began with that number. Yes.
