Hi Peppear,
I feel sorry for you in this situation, looking at the problem from the other side, I can tell you that it isn't an easy thing to quit this addiction. Especially when popular culture tells men that it's not an addiciton, it's "normal."
Thankfully there are websites like this one which offer some support, and remind us that porn 24/7 isn't healthy and normal. The evidence is in the posts and stories here.
I think trying to change someone is nearly impossible, you can't make someone do something they don't want to do, no matter how much you may love them.
Have you considered going to counseling, or maybe writing a letter to him explaining how his addiction makes you feel, and how it has affected your family? That might be a good first step, even though you have talked about it before, writing it down and being specific could really make a difference.
On a different note, if your avatar picture is you, you are very beautiful
I would suggest maybe changing the picture to something a little less provocative out of respect for the people here and their problems
Also, I suggest starting a new thread on the Partners Forum with explains your situation in more detail so you can get more specific help.
Good luck Peppear!
