Michael Madsen files for divorce because he believes his wife drove his son to suicide

Michael Madsen has officially filed for divorce from his wife … claiming he was her victim of abuse for years – and says he believes she drove their son to suicide.

The actor filed for divorce on Wednesday … citing irreconcilable differences in the document – and claiming he had actually separated from his estranged wife, DeAnna Madsenin January 2022.

Although he checked the “irreconcilable differences” box, Madsen also attached a statement to the petition saying that the differences go far beyond mere disagreement.

MM says he separated from his wife in 1922 because he believed that “her neglect, drinking and alcoholism” were harming their son. Hudson to take one's own life.

Madsen adds that DeAnna – whom he married in 1996 – contributed to his problems herself … plunging him into an “abusive, codependent and toxic relationship” that he says ended with his wrongful arrest for domestic violence last month.

As you know, Madsen was arrested last month on domestic violence charges after police say he shoved DeAnna, and posted $20,000 bail shortly afterward.

However, the following week, the Los Angeles District Attorney informed us that they would not be filing charges because insufficient evidence. And now, in addition to the divorce, Madsen is also seeking a domestic violence restraining order.

Madsen's rep told us at the time he was glad his client was able to put the arrest behind him… and now it looks like he's doing the same with the marriage.

Michael's management and publicist declined further comment. We reached out to DeAnna… no response yet.
