What did Jesus's disciples say after hearing his teaching on divorce?

If that's true, no one should get married.

And I say unto you, Whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery.

His disciples say unto him, If the case of the man be so with his wife, it is not good to marry. Matthew 19:9-10
