ET sat down with Rossi last December, after she filed a lawsuit against the Two and a Half Men star. Rossi, who was engaged to Sheen for nine months in 2014, is suing the actor for assault, battery, emotional distress, false imprisonment, and negligence, claiming he was “violent and abusive and uncontrollable” while abusing drugs and alcohol during the time the two were together.

“I’m tired of being scared,” Rossi told ET. “I’m scared of Charlie. I’m scared of the backlash.”

"I still think I miss what we could have had,” she added about their former relationship. “But at the end of the day, he's an addict. He only loves himself, he never loved me."
