In the divorce petition, Cynthia's attorneys write, "Alex has emotionally abandoned his wife and children, and has left her with no choice but to divorce him." The petition goes on to state that the marriage is "irretrievably broken because of the husband’s extramarital affairs and other marital misconduct."
According to papers, Cynthia, 35, wants to be named primary residential parent with shared custody of their two children Natasha, 3, and Ella, 3 months. She wants to keep the family's six-bedroom, $12 million home in Coral Gables. She is also seeking alimony, life and health insurance, private school tuition, and equitable distribution of assets.
Although she signed an antenuptial agreement shortly after the wedding, her attorneys reserve the right to argue that it is not valid.
"Cynthia is tremendously traumatized and devastated," Houston lawyer Earle Lilly told TMZ before the official divorce filing.
Allegations of AdulteryLilly added that infidelity is a "major cause" for the divorce, but not because of any one allegation. Rather, he says, there were a series of dalliances and "Madonna was the last straw."
In a statement to PEOPLE, Madonna insisted, "I am not romantically involved in any way with Alex Rodriguez. I have nothing to do with the state of his marriage."
Madonna is not named in the divorce petition.
As for reports that Cynthia Rodriguez has taken up with Lenny Kravitz, Lilly called her relationship with the rocker "totally innocent." Kravitz has also denied the alleged affair.
"Cynthia is a strong person," a close family member told PEOPLE. "But a wife with two young children can only take so much."
The papers were filed first thing Monday morning by attorney Maurice Kutner. The New York Yankees' star's wife is also represented by attorneys Anthony Sabatino of Miami and John Van Ness of Houston.
