Just joined. Praying for success.

I've been struggling with sex and porn addiction for about 30 years.  I'm married, have 3 awesome children and am very fortunate that our family remains intact today.  The porn issue has caused many issues in my marriage over the years, and it's only by the grace of God that my beautiful wife is still with me.  I've been to several non-Christian counselors over the years trying to resolve these issues.  I'm in a men's group in my church where I recently revealed the issue, but only after my wife caught me viewing porn again, and said she doubted our marriage could survive.  That was 6 weeks ago.  I've been told for a couple of years that I can only resolve my issues by completely turning it over to God, and seeking his intervention.  All other methods have failed.  I pray that the Lord will help transform me into the man, husband and father that He would have me be.  I ordered the book, Return to Grace just a few minutes ago, and look forward to starting that when it arrives.  I ask for prayer, from anybody that would, that I will remain in pursuit of God, seeking his guidance for the transformation I'm going after.
