Why David Duchovny's Wife Divorced Him?

The wild sex life of  David Duchovny is going to cost him big bucks.

The actor, 53- who played a boozy womanizer on his recently-wrapped Showtime hit- is required to pay $40,000 a month to Leoni, 48, plus an additional $8,333 a month to provide for their two children, daughter Madelaine, 15 and son Kyd, 12, according to the terms of their settlement.

The divorce agreement also requires Duchovny to pay for his kids’ summer camp, extracurricular activities, tutoring, private school, college and medical expenses.

 The support payment is based on Duchovny’s $7.9 million annual salary.

Manhattan Divorce Court Judge Laura Drager signed off on the documents on June 18, about a year after the couple filed for divorce from their 17-year marriage.

The marriage began heading south when Duchovny checked into rehab for sex addiction in August 2008.

The star briefly reunited with his Deep Impact star wife, but in 2011, they split up again.

Any hopes of a reconciliation were put to rest in January 2013, when it was reported that the couple listed their three-story New York City home for $9.25 million.

Duchovny, who now lives in a three bedroom condo in New York City’s Central Park West, has recently been linked to his X-Files co-star Gillian Anderson.

Leoni, meanwhile, was spending much of her time with the children until she made a decision to return to work.

“I turned to my 12-year-old son and I said, ‘It’s going to be a little tricky. I’m not going to be around as much. Are you cool with that?'” she said during a summer TV critics’ meeting in Los Angeles last month.

“He said, ‘Yeah, I was getting kind of sick of you,'” she recalled. “So I’m back.”

The actress will play the U.S. Secretary of State in the up-and-coming CBS political drama Madam Secretary.
