Will the Charlie Sheen drama ever end?
Sadly, they fear the worst...
"There have been no consequences," the source says. "He thinks he's the guy who isn't going to OD. Either he will OD one day or someone else is going to get hurt because he gets so volatile."
Family members believe Two and a Half Men has saved him in a way because it keeps him busy and when he's busy he usually stays out of trouble. "But once the show is over, who knows what will happen," the source says. "The people around him now will drop him like a hot potato and won't care what happens to him."
But for Sheen, the show also could prove to be the ultimate enabler, the source says. "His attitude is, 'I'm hot right now. I have a ton of money and my show is doing better than ever. I want to have fun,'" the source explains. "But is he really having that much fun?"
Sheen's rep declined to comment.
