Transcript for New show looks at the impact of money in relationships
All right, robin, now to the age old question for love or money? Well, a new TV show, marrying managers is following couples from different backgrounds as they navigate their relationships and you caught up with one. I sat down with a couple yesterday. He's 61. She's 21. He's a multimillionaire. I heard that wow. She's a former restaurant hostess. They kept the relationship under wraps for over a year but thanks to reality TV, we are all going to see if they're in it as Amy said for love or money. Isn't this fabric beautiful? $6,595 sfwli don't know if I could go back to the lifestyle I had before. Reporter: The new lifetime show "Marrying millions" follows six real-life couples that are hoping to marry. I'm going to ask her to marry me. Mom, are you there? Reporter: But the twist, each couple comes from vastly different financial backgrounds. Can they find love? Or will money come between them. Look what I'm offering you. I don't know if I want it. Reporter: Bill and Brianna are one of the couples on the show. There's a 40-year age gap between them. Bill owns his own company and he's worth millions. The couple insists that their romance is true love. Bri, is this about love or money. Definitely about love. Definitely about love. Reporter: 21-year-old Brianna met bill while working as a hostess at a restaurant and says she had no idea that he was wealthy. I have seen his car whenever we went on a coffee date. But I thought, you know, guys will usually take better care of their car than they do their homes. Right. I didn't find out about his actual wealth, maybe a year after dating. So that's pretty cute. And I know that she doesn't like me for my money. What is it you love about bill. I love his personality. I love his positivity. I love that, well, you actually keep me really positive by the way because I have my cranky moments. You're larger than life kind of person. And bill. I look up to her so much. I look to her for advice. So was marriage in their future? Only time will tell. Of course, the show is like love or money, marrying million, it's geared around money. Would there be a prenup? I think, unfortunately, prenups are part of life these days. It's not very romantic to talk about a prenup. Yeah. We actually haven't talked about that. You haven't talked about it. Would you be okay signing one. No, I wouldn't get married. This sounds like a conversation that the two of you might need to have. Uh-oh. That must be season two. So they are keeping that door open to marriage and children. Now, bill is older than both her mother and her father. He has children that are older than Brianna and she says it took some time but, Amy, her family has completely accepted their relationship despite that 40-year age gap. All right, Paula. Thanks so much. We turn to Dr. Jenn Mann, author of "The relationship fix." She joins us now. I think we all know marriage is tough no matter what but if you have a huge age gap what are some of the struggles. Not just the age gap, I the financial gap between the two of them and what you have to keep in mind is that when you have a gap that big, it's not unlike when you marry someone of a different religion or disk culture, you're going to have different ideas about everything from raising children to how you want to take a vacation to how you handle success and goals set so it's very different, almost a different culture. Whether or not you have a prenup. Exactly. You heard that. It's amazing these two haven't discussed this yet. That's a red flag for me. You say this makes sense, if you've got such a big financial gap it can truly lead to a power struggle. Absolutely because money is power. And the person who has the money is ultimately the final decision maker and typically some of the issues that I see are these power struggles because people act out their relationship issues and struggles through money and through power, also I tend to see a lot of situations that come up where people get entitled. Tend to be two type of the people. Those who get entitled and those that are gracious and makes them appreciate the other person even more and then also the other shoe is withholding. Sometimes the person with the money will withhold and play out that power. You want have those golf clubs. That's not okay and typically that results in a lot of resentment. Any tips in navigating this if you're in it for love and have all these big differences? Make sure that you have a system in place to help negotiate difficult decisions, bring in experts. For the psychology part bring in therapists or a religious leader and have a business manager, an accountant you use. Make sure it doesn't matter who has the money you need to have these suggests respectfully no matter who has it. "Marry millions" airs Wednesdays on lifetime.
