I heard rumors about Einsteins wife; that she was the brain behind it all... Is that cheating on your wife?

"There is clearly a link between Einsteins success and his genius wife Mileva Maric. I would go as far as saying that she was a major contributor to theories he published for several reasons. When Mileva asks Einstein for money if he earns Nobel price he gives in without opposition. What kind of leverage she had for him to do so? Ever since they separated Einstein has not produced anything significant. His communication ability and founded on papers published in 1905 made him famous but all his future work was invalid and even contradictive of his famed work. If Mileva arrived to e=mc2, as a women scientist, she would have very difficult time being taken seriously. Finally, the whole secrecy about his first marriage is suspect as well."
