Congratulations on taking this bold step, Jimmy James, and welcome to RBN.
There are peaks and valleys along this journey, but if you keep coming back and sharing your progress (and pitfalls) as well as chiming in on others' journeys, you'll find a network here to help you stay the course. Just journaling can be a powerful antidote to acting out.
I can relate to so much of what you shared. I discovered PMO in college. Raised in a Christian home with very strong sense of right and wrong, and this was my outlet that didn't involve drinking, drugs, premarital sex, etc. It was something I could do, could hide, and could feel safe with. And I carried it into marriage, into parenthood, and finally had to reconcile that, at 47, I am not the man I wanted to be, the husband I want to be, or the role model to my kids I want to be. (even though my kids don't know, there's no denying the time and energy I spent around my addiction could've been better utilized in more positive efforts)
Do all you can to take your wife on this journey with you, respecting her boundaries around what she does/doesn't want to know, of course. Having your partner supporting you and keeping you accountable is huge. For me, hiding from my wife was both shameful and exciting at once. It creates confusion. It creates distance and disconnect. The past 2-3 weeks, we've had more heartfelt conversations and honesty about what we want and what we believe than we have in far too long, because I no longer have a closed door full of secrets. Gauge how much you feel she wants to be a part of the process, but let her in as much as she is willing. It is a powerful thing, taking the journey together. And what she feels she can't be a part of, rely on others - this forum, a counselor, clergy, or therapist, a step group, a trusted male friend, whatever works for you.
We look forward to being here with you as you reboot and reclaim the life God intended for you.
