This woman has a dull, dull heart. Her questions are all about herself. Jesus got her attention with the question about her husband.
The part no one talks about seems to be the heart of this conversation -- God is seeking worshipers. That's it. Why else would a messiah and an immoral Samaritan woman meet at a well in the middle of the day. The Father is seeking her! When she saw God was a seeker she wanted to talk about the Messiah. . . finally!
