The wife of George Zimmerman, Shellie Zimmerman, spoke with "Good Morning America" Friday in an exclusive interview with ABC's Steve Osunsami.
Shellie filed for divorced after standing by her husband during his trial for the shooting death of 17-year-old Trayvon Martin.
George Zimmerman was acquitted of the charges against him.
"I have been married to a person for almost seven years and I don't think I ever really knew him at all," Shellie said.
Shellie said she's filing for divorce from her husband because, according to her court filings, their marriage is irretrievably broken.
"Do you think that he feels, perhaps after the trial, more invincible?" Osunsami asked.
"Yes. In my opinion, I think he feels more invincible. I just think he's making some reckless decisions," Shellie replied.
Hours after the divorce papers were filed, George Zimmerman's defense attorney, Mark O'Mara, appeared on CNN in his defense and also in his new role as a legal analyst.
"It would be nice if he could move on in his life in some form or fashion," O'Mara said of his client. "I don't think that will ever happen."
Since his acquittal in July, Shellie said George had spent maybe three or four nights at the Sanford home they shared, and she moved out Aug. 13.
Shellie said George has a temper, she said he was verbally abusive, and she said they went to counseling, but it wasn't working.
"I have a selfish husband and I think George is all about George," she said.
Shellie has had legal troubles of her own. She pleaded guilty to lying in June of last year at a bond hearing for her husband about how much money they had.
Shellie said, "I stood by my husband through everything, and I kind of feel like he left me with a bunch of pieces of broken glass that I'm supposed to now assemble and make a life."
She's also hoping she can leave behind the drama that has taken over her life since that fateful night in Sanford.
"It's just time. I have supported him for so long and neglected myself for too long, and I feel like I'm finally starting to feel empowered," she said.
Shellie said she is asking for their two dogs, and a share of whatever her husband might win in a defamation lawsuit he's filed against NBC.
