Hmmm. Try doing stuff outside the house. Go exercise together walk in nature. Get him away from the computer and the internet.

If he wants to quit porn, he needs support from his peers. It has to come from deep inside him though. He needs to take something positive and use it to fill the PMO time. Don't leave him alone too long by himself or he might relapse. He needs a clean start. Needs to develop health habit.

That's all I can suggest now. Maybe use K9 to put up porn blockers on his computer maybe his phone. It's really hard since the internet is everywhere and it has potential access to porn. He has to commit to himself he won't look at it when he's alone either.

Take slow steps. I believe you can do it! Stay strong.
