Sorry Lauren but I really must disagree strongly. Monogamy is not a myth for those of us that believe in it. And it's certainly not a myth for the wives and partners of married men who visit escorts. It's as much a lifestyle choice as any other. Just because it's not as risqué as some, doesn't make it any less credible or worth committing to.
Where one partner in a relationship is basically lying to the other then the relationship has become a lie.
I'm not a fuddy duddy by anyone's standards but I do believe in honesty and being open to people you claim to love. Many couples enjoy open relationships or relationships with three or more parties and if that works for them that is fantastic but when someone is being lied to, then it's just not good, no matter what spin is put on it.
