Elizabeth realizes something in herself that she reveals in these words:
John, I counted myself so plain, so poorly made, no honest love could come to me! Suspicion kissed you when I did; I never knew how I should say my love. It were a cold house I kept!
Essentially Elizabeth is confessing that she has been judging John all along. At this point she doesn't believe she has any right any longer to judge him. As he continues to ask for her judgment, she refuses to give it and expresses that he deserves the opportunity to be his own judge because she realizes that she pushed him to another woman. As John expresses a desire to have his life, he asks for Elizabeth's opinion, but she refuses to pursuade him in one way or another. If there is anything she can do for him at this point, she feels that she should let him make his own decisions.
