Could This Woman Be Trying To Poison Her Husband? (VIDEO)

Nikki claims that her husband of three years, Mark, has punched her in the face, broken her nose and run over her toe with his truck. "Mark became violent with me soon after I was pregnant with our oldest daughter, and it has escalated over the last three years,” she says. “Mark and I fight and argue daily. It’s a chaotic home.”

Mark admits to hitting Nikki once but claims that Nikki instigates most of their fights, has violent outbursts, and thrives on playing the victim. He even believes Nikki may be trying to poison him. “I am not an abuser,” he says. “Battered wives are scared and timid, because they’re afraid they’re going to be battered. My wife is the exact opposite. My wife will nag, push me and slap me. She has punched me.”

Watch the video above as he explains three instances when he suspects Nikki attempted to hurt or kill him.
