NFL legend TROY AIKMAN and his wife Rhonda are breaking up after 10 years together.

Troy issued a statement saying, quote, "This has been a difficult decision for Rhonda and me, but after 10 years of marriage we have decided to separate.

"We remain deeply committed to our children and respectfully ask that you honor our family's privacy during this period of adjustment."

Troy and Rhonda have two daughters, ages 8 and 9.  Rhonda also has a daughter from a previous marriage.

This was Troy's first marriage.  In the '90s, he dated country singer LORRIE MORGAN... and may have also hooked up with  SANDRA BULLOCK and JANINE TURNER.

Aikman quarterbacked the Dallas Cowboys from 1989 to 2000... winning three Super Bowls along the way.

These days, he calls games for Fox.
