One reason that a porn habit is so destructive to a marriage

What is the main reason that a porn habit often leads to divorce?  The emphasis is on the word “main” because there are many reasons why this is toxic. The main reason though, according to our unscientific inquiry into the matter, is that for a lot of women (our control group comprised only straight couples so we are only referring to straight marriages when we speak on this issue) porn is DEGRADING. For a woman who is in a marriage with a man with a major propensity to resort to porn whether in her presence or outside her presence, she begins to resent him because she feels like he repeatedly and continuously DEGRADES her with this. What is the solution? How can more marriages be saved? Just don’t watch that filth and certainly stop subjecting your wives to porn because each time you do that she feels like you have DEGRADED her. This shouldn’t be rocket science, guys!
