You know the saying, "Once a cheater, always a cheater," but is it true? If you've ever been burned by a sneaky mate, you're familiar with the heartache it causes -- not to mention the suspicion that can last for years.
On Temptation Island, we see firsthand how's Javen Butler's past actions continue to torment Shari Ligons. Although it occurred while the couple -- who has been together for the past eight years -- was in still college (and, according to Shari, was not an emotional affair), that doesn't mean she's completely over it.
The four couples who went on Temptation Island are there for different reasons, and for Shari, it's the ultimate test of whether or not she can finally trust her boyfriend. To break down the myth of "Once a cheater, always a cheater," we turned to resident relationship expert Tracy McMillan, author of Why You're Not Married . . . Yet: The Straight Talk You Need to Get the Relationship You Deserve.
"Here's the thing about cheating," McMillan told USA Network. "If a person is willing to cheat, that's a very specific character. And in order to change that character, it's not going to be the simple passage of time. They're going to have to turn the Titanic around."
And so what would it take to right that ship? "That is a years-long process, probably, involving a lot of therapy, a lot of self examination," McMillan said. "If you're hoping that it's been two years, so the person's not going to cheat any more? Time isn't going to do it; effort's going to do it."
The verdict: "I'm not saying everybody who cheats is going to cheat forever, but they're going to have to do some major work on themselves in order to not cheat any more."
Temptation Island airs tonight at 10/9c. Stream the first two episodes on USANetwork.com and in the USA App!
