Answer:
In Act 4 of The Crucible, the problems between John and Elizabeth Proctor are not fully resolved, but there are indications that they are on the path towards reconciliation.
Throughout the play, John Proctor has been struggling with guilt and shame over his affair with Abigail Williams. His confession to adultery was a significant step towards his personal redemption and an attempt to clear his conscience. However, his relationship with Elizabeth has been strained, and she has had difficulty trusting him after his infidelity.
In Act 4, Elizabeth shows forgiveness towards John when she tells him that she has forgiven him and takes responsibility for his adultery. She also tells him that he needs to forgive himself and live for himself. John, on the other hand, is still grappling with his guilt and shame and is uncertain about his future. He tells Elizabeth that he cannot judge her decision on whether or not to testify against Abigail Williams and the other accusers.
While their conversation in Act 4 suggests that they have made progress towards resolving their problems, there is still some tension between them. John is still uncertain about his future and is struggling to forgive himself fully, which may make it difficult for him to fully repair his relationship with Elizabeth.
