I Have Habitually, Continually Lied to My Partner! Is There Any Hope for Me and Us?

Porn, Betrayal, Sex and the Experts — PBSE

In Episode 219, Mark & Steve get super passionate in addressing a heart-felt, yet tragic submission from a PBSE listener. Here's what he had to say—
Hi, I would love it if you guys could do a podcast around the effects of years of lies and trickle truths on a full disclosure? I've been a PA for 18 years roughly and i've had a hard time coming to terms with my addiction and its consequences. My partner and i have been together 4 years and she found out 1.5 years ago that I was being unfaithful through my excessive pornography and social media consumption.
I have always had a hard time running away from conflict and I have a history of communication trauma and sexual assault in childhood. I done everything wrong with my partner, I lied and lied time and time again, I minimized and justified my actions where I felt I could and for most of my "recovery" I just found sneakier ways to access pornography and just flat out refused to be accountable for the hurt it would cause my partner in these moments. I don't think my addict brain could fathom accountability at these low points.
I allowed my partner to dig through every site/app/device and find just troves of visits to profiles and video history, bank transactions. This happened hundred of times over the year and with each new item discovered my partners pain Increased. I had every opportunity to be upfront and honest to my best friend and partner but I was reluctant to let go of that fear. Its like my addicted brain was convinced its easier to sprinkle dust onto her than to drop a ton of bricks but thats just not true at all.
Unfortunately i have realized a lot of things too late for my partner at this point and we have just recently moved into a state of in house separation. We both have CSAT therapists but are in very early days of this and still have a long way to go. My reason for reaching out is due to the fact that my entire life at this point (our relationship/my dog / my home/my job) relies on openness and full disclosure. Is there any hope that I can ever navigate around the fact that i allowed my partner to be the detective and she uncovered at least 95% of what I've done with a measly 5% being my efforts. We have spoken for a year and a half about aspects of my addiction and I struggle to dig deep and expand on my occasions of acting out. This coupled with lack of honesty just breeds an environment for my partner to rightfully wonder, "What the hell do I not know? " I'm sorry if this seems a bit all over the place , but I’ve tried to express my situation the best I can. I appreciate the work that you guys and everyone involved do to make this available for people.
- Why do habitual lying and addiction nearly always go together? Why do addicts fear telling the whole truth and being "seen" in their totality?
- When a relationship account is SEVERELY overdrawn and operating from a deep deficit, is their any hope for reconciliation?
- Why is acceptance of, accountability for, and consistent verbal acknowledgment and validation of the pain the addict has caused, CRITICAL for both him and his partner?
- How can the addict use the "language of safety" and the ACTIONS that follow it to show true empathy, real amends and lasting change?
- Proactive, DAILY transparency, not just around sobriety, is essential!
- Why the addict must PRACTICE daily vulnerability, not only in his marriage, but in all his relationships.
- What place does "Formal Disclosure" have in this process?
