Welcome [s]Y2K[/s] Y2BF
Sounds to me like you're committed to freeing yourself from lust and you have a reasonable plan A.
Full commitment is key. That means no sneaking peaks or fantasies here and there.
I agree that the bigger picture is, well, the bigger picture. Consider making a date night once a week with your wife where you can go out and just talk.
As was discussed elsewhere on this forum just today, getting sober is just the first step. Getting sober means stopping acting out (whether in your mind or in your pants). The next bunch of steps relate to recovery. For you in particular, this means getting out of yourself, out of your fantasy world and into reality. When we were young we learned to escape into fantasy for various reasons. As adults, although the reasons may no longer apply, the habit of escape is ingrained, and the addictions associated with that escape are even more deeply ingrained.
It will be a process, but one certainly worth the effort. The reward will be life itself.
Hatzlocha!
