Compare and contrast Benedick's and Beatrice's conflict to Claudio's and Hero's relationship in Much Ado About Nothing.

These two couples are very
different.

It would seem that the relationship between Hero and
Claudio is immature.  They are attracted to each other physically but they really don't know each
other, otherwise Claudio could not be convinced that Hero was unfaithful.  It would appear that
he trusts the word of Don John over his intended.  Don John has not proved to be very
trustworthy, yet the men believe him.  Cleverly Don John plants the seed.  Claudio excepts it. 
When he learns of the deception of Don John, he takes a journey where he grows and hopefully
matures and becomes worthy of Hero's love at the end of the
play. 

In contrast, Beatrice and Benedick don't want to rush into
any commitment.  In fact they can't admit to themselves that they love each other.  They are each
guarding their hearts.  They need their friends to help them realise that they, in fact, love
each other.  In fact Benedick's love for Beatrice causes him to side with her over his best
friend because he trusts her.  If she says Hero is innocent, she must be
innocent.

In the end, it is a matter of trust.  Claudio does not
trust Hero; Benedick does trust Beatrice.
