How much should I (do I) want to know about what my spouse does when viewing porn?

This depends on you.  You have 4 options:

1. Do nothing, know nothing and go on as if life is just fine. (It won’t stay that way.)
2. Know every detail of everything. This can be dangerous because detail can get in the way of forgiveness.
3. Know the “types” of things your partner has done.
4. Know the basic actions – watched porn, went to a sex shop, had an affair, visited a prostitute – so you know how to protect your marriage.
5. Simply know they are addicted to porn or sex and try to move forward.
