"I have found the one. I am in love, without a doubt. I do see her as the one I want to marry and spend the rest of my life with," Mesnick toldPeople in a Friday report.
"Everyone has been through ups and down in their life, and there are no guarantees when talking about love. I am living proof. I got married before and thought I'd be with her until death do us part, but we all know how that worked out. That said, I am very much in love and very hopeful."
The single father from Seattle will present his final rose to either Melissa Rycroft or Molly Malaney during tonight's pre-taped The Bachelor thirteenth-season finale broadcast -- and Mesnick said both bachelorettes are "amazing," making for a "very, very tough decision."
"Melissa is really that ultimate woman that is going to stand by your side forever. She's fun. She's beautiful and exciting and willing to try new things," he told People. "Molly is the balance of a lot of different things. We have a great friendship going. There's passion there. She's got her eyes wide open to the world."
"Without a doubt they'd be great. If I was sitting in the producer's chair right now, I would be hard-pressed to chose just one of them," he told People.
"There's Stephanie with her story and how giving she is and how strong. And Jill was the backbone of the girls here. If I were in charge, I would have two simultaneous Bachelorette seasons going at the same time. Two mansions side by side, 50 guys, two girls. I think maybe they could work out twofer deals on helicopters."
