Sobriety may be the end of Ozzy Osbourne and Sharon Osbourne
It’s highly possible that his sobriety changed the relationship. After being sober for more than three years, Ozzy was clear headed enough to take a look around at the life he had made for himself, and didn’t like what he saw. He decided to just scrap everything, including the family he had, and start over completely to build the life he wants now.
It’s possible that Ozzy, now sober, has decided he doesn’t want what he wanted when he was an addict and that making a fresh start is the only way he can see moving forward with his life. It might not be fair to those who stuck by their sides through the worst of their times, but what more could a person expect from a lifelong user?
