Martie,
The Prophet is and has been very distinct in his counsel to ALL men who hold the Priesthood on this matter of which you speak. It is always covered in the General Priesthood session of conference. The wonderful brothers and sisters who have expressed their support for you in this forum speak from their hearts, from testimony and sadly, from experience in some cases. You love your husband and your family, it is evident. You are concerned about keeping your family intact. Martie, you are a daughter of God and as such deserve the divine respect which He wants you to have. After all that's been said in this forum, and your suffering, is there any doubt this problem of your husband won't eventually destroy your family?
While serving as a Stake High Counselor, only men ever came before us in disciplinary counsels, and always for sexual transgressions. Pornography almost always played a part in their downfall. Whether you've been married in the temple or not your Bishop AND your Stake President have an interest in your family that is real and genuine. If you feel in going to your current bishop is not working then go to your Stake President. Yes, as an earlier comment said, your husband is in denial, he also is not being truthful, honest or honorable. I'm very sorry. Now it is your children, the innocent who have to be protected. This is not what a Celestial marriage is make of. Being a man in this society or any is not an excuse for any use of pornography or lusting after other women. Either he is true to his covenants or he is not. There may be some things that can be drawn out over time for an improvement to emerge but his problem is not one of them as it will only get worse. Go your your Bishop or Stake President. You have the support of Jesus Christ and his prophet.
I add my prayers to others on your behalf.
O.
