And that's more often the case these days. U.S. census data revealed earlier this week that more than half the Americans who might have made it to their 25th wedding anniversaries since 2000 got divorced, separated or widowed before reaching that benchmark. The data reveals that for the first time since World War II, couples who got hitched in the late 1970s had a less-than-even chance of remaining married 25 years later.

You've heard of the seven-year itch, the restlessness that occurs in a marriage after seven years —allegedly — and if not, the brilliant movie starring Marilyn Monroe. These days, some experts think the seven-year itch is happening even earlier, say around three years. People start getting bored, they're looking for an adrenaline boost — a little romance and excitement — the kind you can get from a new partner.

First Wives World's Debbie Nigro commented on the new census data and trends in a piece today on the "CBS Early Show." Debbie noted that one of the problems is that for some people, "commitment" doesn't mean "commitment" any longer, or doesn't mean "commitment" to a single person for life. "It's ‘commitment' until I say it isn't." Marriage, Debbie told the "Early Show," is a "work in progress." To be sure, it is a relationship that requires understanding, empathy and a commitment to working on it throughout your life.

CBS also interviewed famed divorce attorney Raoul Felder who said he really does see the seven-year itch. "For seven years they [couples] stay married, eight years there's a divorce." Can people learn from their mistakes? Felder says sometimes people are so exhausted by their second marriage that they don't want to go through all the agony again and opt for a quick divorce.

Felder says the divorce statistics are deceiving, and that somewhere around 65- to 70 percent of all marriages are unhappy, even if they don't result in divorce. People stay together for financial reasons, all sorts of reasons. And the most marriages and divorces he's ever seen? A woman who went through seven divorces and is now on her eighth marriage! Naturally, Felder wouldn't disclose whether the woman is a celebrity or public figure.

There's no question that divorces are more common now than they have been in the past, but what do you think? Is it really the seven year itch? What is it that's causing so many marriages to break down?
