Why did howard hewett and nia get a divorce?

Howard was let go from his record company at that time. He started trying to run her career, starting many arguements between them; she got tired of it. Rumor has it, he is a unfaithful man to the wives he's had. There's a rumor going viral that his current wife is filing for divorce for this such thing. He is a very conceited person with a bad attitude at times.
