Try consulting the text before you make pronouncements like that. Matthew 5:31-2, also 19:8-9:

It hath been said, Whosoever shall put away his wife, let him give her a writing of divorcement. But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery.

Mark 10:11-12:

And he saith unto them, Whosoever shall put away his wife, and marry another, committeth adultery against her. And if a woman shall put away her husband, and be married to another, she committeth adultery.

This is Jesus speaking in both cases.
