A new trend has some couples turning to lawyers to help save their relationships. “I promise you that I am going to be making sure that you’re having more fun, more dates, and more time of mine,” Gregg Sullivan told his wife, Toni Mantus. But unlike many of the promises made during a relationship, this one is part of a written contract. The couple told CBS 2′s Dick Brennan that, with the help of an attorney, they have put everything in writing, including how often they have sex.
