In the crucible John Proctor says It is winter in here yet what does he mean by this statement?

He is calling his wife cold, not as in the temperature,
but as in the attitude or mood. You may have heard the phrase, "giving the cold
shoulder". This means that someone is ignoring or being rude by way of not saying
anything. This is what Elizabeth Proctor has done to
him.

She later admits in the play that it takes a cold wife
to prompt lechery. Essentially she is saying then that she shares blame in the problem
of their marriage that caused John to look elsewhere for pleasure and satisfaction. She
notes that she wasn't delivering the affection required in a marriage
relationship.
