The recent altercation between George Zimmerman and his wife, reported Monday after she called emergency services saying her life was in danger, might have stemmed from an incident where she made allegations that Zimmerman was having an affair with his former fiancée, reports said.

Zimmerman, acquitted in July in the murder trial for the shooting death of black teen Trayvon Martin, was engaged to Veronica Zuazo, a beautician, before he married Shellie in 2007. But the former couple’s engagement ended after Zuazo filed a domestic abuse complaint against him, Daily Mail reported.

“George has been having an affair with his ex-fiancée. Shellie believes it flared back up after the acquittal,” John Donnelly, a friend of Shellie’s, told Daily Mail. He added that Shellie’s only contact with her husband since his acquittal July 12 has been through text messages.

“During the trial, they were sequestered, moved from house to house, so there just wasn't any opportunity for anything like that [an affair] to go on,” Donnelly said. “To the best of my knowledge and hers, this started up after the trial.”

The publication reported that Shellie had given Zimmerman an ultimatum, asking him not to bring Zuazo into their house. But three weeks ago, Shellie saw Zimmerman and his former fiancée pulling into the driveway of their Lake Mary house in Florida, which prompted her to file for divorce.

Explaining her reason for filing for divorce after six years of marriage, Shellie said during an appearance on Good Morning America last week that she believes her husband has become selfish after he was acquitted in the controversial shooting of Trayvon Martin.

“In my opinion, he feels more invincible. I think he's just making some reckless decisions. I have a selfish husband. I think George is all about George.”

She said that Zimmerman had a fierce temper and often “beat her down.” The Daily Mail report also noted that Zimmerman and Shellie had been in marriage counseling sessions to curb his “anger management issues” before the Feb. 26, 2012, shooting of Martin in Sanford, Fla.
