I know nothing about her. But being Bill Cosby's wife all these years would have been a hell of a fine meal ticket. That may or may not have been a factor. She may simply love him and want to be by his side, whatever, until death do them part.
In pictures she's nearly bald; looks maybe like chemo for cancer. I'm not going to disparage someone who's been through that.
They married young. Her parents were opposed. Married within a year. At one time she was considered beautiful.
I was under the impression her hairstyle is African.
When the first got married, the bought a huge mansion in MA. It was at the beginning of his career. It was decided that she would live in MA year round. He would live in LA while his career was going, and circling back to MA.
That went on apparently for decades. But they spent a lot of time apart.
