What conflict exists between abigail and proctor?

Conflict between Abigail and Proctor:

When the play begins, is the Abigail's obvious animosity toward Elizabeth Proctor, John's wife.  In Act One, the pair discusses their past relationship as well as Abigail's continued devotion to John, also to his admission that he still have feelings for her too.

But John doesn't get mad until Abigail begins to criticize his wife at that time, and started quoting but before she  ends saying it John cuts her off. However, Abigail continues, She is defiling my name in the village!  She is telling lies about me!  She is a cold, snivelling woman, and you tend to bend to her! John threatens to whip her.

John's continued feelings for Abigail created conflict between himself and Elizabeth in Act Two, when he hesitated to tell the magistrates what Abigail had said to him about Betty's illness having nothing to do with witchcraft.  The conflict between John and Abigail revives when Abigail tries to frame Elizabeth for the claimed witchcraft .
