Rather than losing your spouse to the 7-year itch, you might need to worry about losing him or her once you add a kid to the picture or so says a new study.

The Modern Love Report, commissioned by USA Network  and released today, reveals that once baby is on board, parents are far more likely than non-parents to abandon ship. Parenthood is arguably the driver of infidelity – 55 percent of couples married with children say "marriage is more difficult than I thought it would be," vs. only 34 percent of childless married couples that feel the same. The MODERN LOVE REPORT was conducted in conjunction with the premiere of USA's new original drama series, SATISFACTION, which examines marriage at its midpoint through the lens of one couple who grapple with the question "What do you do when having it all is not enough?" The series premieres at 10 p.m. tonight on the USA Network.

But seriously, is your kid ever to blame for a marriage gone bad?
