I completely disagree. Not to embark on religion and God dialogue, but God has no role in this ordeal.

The wife has natural feelings to look elsewhere to fulfill her sexual desires. It isn't her husband's fault, or children, but rather that for some reason, she desires more excitement.

What should she do?

First confront herself and see if there is something she can change in herself to compromise her sexuality with her husband's. Maybe he is turned off by her for some reason, and she doesn't feel desired. They should talk. If it doesn't get better, she should go mess around on her husband and see how she feels.

Only by doing things, do we learn how we really feel. The mental ruination over wondering about things...is more intense then the actual thing.
