Baby Boomers are calling it quits more and more these days, divorcing at a surprising rate.

A recent article says one in every four marriages that fail occur with people 50 years or older.

Divorces among the baby boomer generation double from 1990 to 2010.

But why are couples waiting so long to split up?

We talked to a psychologist to find out what's behind this so called "Gray Divorce."

"I'm 56 years old, I've been divorced since December 2012, and I'm happy about it, it's all about me now," said Sandy Allin, one of the many Baby Boomers beginning a new chapter in life.

Sandy adds, "There’s a lot to be said for the freedom to do what you want and take care of yourself for a change...I do whatever I want, travel whenever I want, it's kind of great."

Sandy says she waited for the right time to make the big decision. 

"The reason I got divorced later, is to make sure my kids were old enough to take care of themselves," said Sandy.

And she's not the only one her age moving on from a rocky marriage.

"It's not uncommon for people to say we're going to stick it out at least till the kids are out of the house, and now it's empty nest, do we even know each other, much less like each other?" said psychologist Michael Costello.

A recent article by USA Today says more and more of the generation are splitting up after experiencing a "second mid life-crises."

"You know, I haven't accomplished everything I wanted to or experienced everything I wanted to. my time seems limited... when we start to recognize that, you can almost get a mild sense of panic."

"When you get older you realize life's too short, so it's time to look at the future. are you happy with where you are? If your not, you need to do something about it instead of being unhappy," says Sandy.

Experts also say today’s society is more accepting of divorces as a solution to unsatisfying marriage.

"It's probably easier and more acceptable now...women now, they can get what they want by themselves, and years ago people had to depend on the man, we do it ourselves now," said Sandy.

Financial experts say the biggest downside to the so-called "Grey Divorce," are the economic challenges, especially when it comes to retirement plans.
