Let me clarify a point since I can't edit my post :

When I say "I don't caer what he's doing" I mean the activity he's doing that's hurting her is of little importance to me relative to the results he's producing.

If he's doing something to harm his wife and their marriage he needs to knock it off and communicate with his wife.

You don't just keep doing it and ignore your spouse.. that's just passive aggressive abuse...

And I would argue a strong sign that he is in fact addicted.

If he's willing to ignore his wife's hurt to consume porn even after she's implored him to end the behavior then he's very likely addicted now...
