She has also dropped an order of protection against him.
"I want to work on my marriage, and I love my husband," Hardiman's wife said in court Tuesday.
Hardiman, the former leader of the anti-violence group, had been accused in May of punching and kicking his 47-year-old wife, leaving her with bruises, a cut to her neck and a swollen lip. In a June court appearance, her lawyer said she was "beaten like an animal."
Hardiman has said he "did not touch" his wife, who filed for divorce last month.
Hardiman's wife declined to comment after the hearing in Maywood on Tuesday. It was unclear whether she intended to withdraw her divorce filing.
Hardiman, after court, said he had no idea she was planning on dropping the charges.
He said he's "grateful" to his wife.
"I love my wife and that's a reality. I hope we can reconcile and take care of our business," he said.
Shortly after Hardiman's arrest, Cure Violence, the parent organization of CeaseFire which is affiliated with the University of Illinois at Chicago, announced that it would not renew Hardiman's contract when it expired June 30.
When asked what his next step was, Hardiman choked up and had to pause to regain his composure. "My next step is to revive my career," he said.
