Is this something that makes marriage successful. Or is this something that you shouldn't have to worry about in the first place? Here are the two rules that Avril and Chad have so they don't have to worry about cheating on eachother... or you could JUST NOT CHEAT ON EACHOTHER!


No drinking."We don't drink when we're apart," says Kroeger. "Ever. Even if we're apart for weeks." Lavigne says that it's just the responsible thing to do. "We want to protect what we have," she says.

No nightclubs. "We don't want to go anywhere that you're asking for trouble," says Kroeger. He adds, "I don’t want to be in Europe texting her, like 'Where are you?' " he says. "This way we don't have to worry about any of that stuff."
