What indications are there that the Proctors (John Proctor & Elizabeth) are, in spite of their differences, a united and loving couple?in The...

For the most part, the reader sees that the Proctors are
working through their differences.  I think that a strong case can be made that there is
much upon which to build in terms of their relationship in Scene 2.  The two of them are
able to talk about the fact that the affair with Abigail still causes hurt to them.
 Neither of them shy away from the fact that John strayed outside of marriage and the
implications of this.  They demonstrated a great deal of courage in openly talking about
how John feels that he is not trusted and how Elizabeth still feels hurt by the affair.
 A case can be made that the only reason this discussion happens is because they still
have feelings of devotion towards one another. If they lacked feelings of love and
loyalty to one another, the discussion would simply be avoided by either or
both.

The devotion and united nature of their relationship
is demonstrated when the outside world begins to encroach upon their sense of home.
 Reverend Hale's presence bring this out first in that both of them stand by one another
(Even though John forgets the adultery commandment, something that Elizabeth brings out
subtly and without repetitive venom.)  When Cheever comes to arrest Elizabeth, John's
devotion to her in both telling her that he is going get her out of jail and his intense
response to Herrick for using chains to take her away are both representative of how
much they love one another.

Naturally, John's vigorous
pursuit of her defense at the courthouse also represents a commitment to her. This is
actually seen in a deleted scene from the production where John meets Abigail the night
before she is to go in front of the court.  He tells Abigail both through words and
forceful action that his wife will not be sacrificed. Although deleted, this scene is
indicative of the loyalty he feels towards his wife, and although there are challenges
between them, the courage it takes to confront Abigail privately is representative of
the love he has for her.  When he stands in front of the court and calls out to
Elizabeth that he has already confessed, there is a feeling that they are both united in
their love for one another.  When the play ends with Elizabeth's protestation that "God
forbid I take it away from him" in reference to his goodness, it is a moment where she
recognizes how important his name is and for this, she will make the ultimate sacrifice
of losing her husband in order to protect his name and reputation.  This love for both
husband and his honor is mirrored by the love he demonstrates for his wife, despite his
failures and shortcomings as a husband.
