This is a predominantly women's site and you've chosen to comment on a thread where women are very upset about the deleterious effect on their sex lives and relationships of men wanking themselves to porn to the point they can't have sex with their wife. Some of the women here also find porn a form of cheating. Many are also disgusted by porn itself because it involves rampant sexual exploitation of vulnerable girls and women, not to mention the heinous violent nature of a lot of porn. Then the temperature on the thread was raised by a mansplainer who came along to cheerily inform the OP that she's exaggerating, because he can get it up with his wife and HE wanks to porn 3 times a day. He then happily told everyone that he is not bothered in the slightest by the ethical issues in porn and he even said that women are exploited in other work places anyway, so what's the problem? Cue mass revulsion.
So you, a bloke, come on this thread to ask the OP:
"Did you leave him, in the end? I assume so, as it didn’t sound like there was any action he could have taken that could have turned things around for you."
Coming from a bloke, that sounds accusing to OP and commiserating with the pornsick H: poor man, he can't do anything right.
Women are rightfully sick of the bro-code, where men either whitewash the shit behaviour of other men or blame women for it. So suggesting that OP is a meanie who won't give her H a chance to redress the problem is going to be met with staunch opposition on this thread.
You then take something that OP said as definitive - that she's lost the desire to fix things by forcing her porn-sick H to stop porn and drag him to therapy - and you pick a fight with @SirRaymondClench when she says the situation is not black and white, that if the H did ANYthing to address his wife's concerns, she might have stayed with him.
I concur with her assessment btw, and so would every other woman reading this.
Then you accuse her of a strawman argument, which seems like a case of projection.
So your entire exchange here has unnecessarily put people's backs up, and suggests that you're not here wanting to understand something, rather, you want to troll the thread out of spiteful male aggression.
There's plenty of such trolls on MN. I don't think you're one, having read your thoughtful comments elsewhere on topics that do not relate to porn. That's why I am bothering to explain what you've done wrong here. Otherwise I'd ignore you.
If you really wanted to know whether the pornsick H could have turned things around (yes, it's possible), you should have read the room that you're standing in and couched your question more respectfully.
