To LifeDestroyer, firstly, as a WW, I am so sorry you are here. My BS and I have been following both your journey and your BS as we have been looking for solid advice from others who have been in this same position to help us through this ourselves.
This is also the first time I am posting on any forum, so I will apologize in advance if I divulge too much information, not enough or am inappropriate. Fair warning, I can be long winded (insert feeble smile here).
I am not sure how to start, or where to begin. But here is a brief summary of our life:
17 years ago, I had my first affair on my BS while I was working an extra job as a bartender with a regular customer, he didn't divorce me, he forgave me. I didn't give him a timeline, I didn't talk about the sex, I didn't continue going to IC, We didn't continue with MC (from what we have recalled together, the therapist made my BS take 50% responsibility), I 'rug-swept' the affair and focused on 'making everything better'. We were living in a small town, sold the house and moved away from my AP.
We had 3 young boys at the time (each of us had one from previous relationships, and one together). My BS loved me and his family so much, he ate the shit sandwich I gave him. I asked him to marry me in 2006, to prove to him that I loved him, and we did. But the first affair eroded away our marriage, our relationship. I didn't do what was necessary...not even the bear minimum to create safety for him. I wasn't transparent, I didn't help him rebuild himself, from the humiliation I put on him. The emasculation. The distrust. There is so much I didn't do...
In those years since the affair, our youngest was diagnosed with PDD-NOS (Autism Spectrum) and began having full tonic clonic seizures. Life started throwing crap at us left and right, and we were alone, we didn't have family or friends for support. We were told not to expect him to even graduate highschool...he did.
Its now 3 years from D-Day of my second affair. An affair I had promised wouldn't happen 17 years ago.
I am re-doing my time line, during my 2nd affair, I wrote a journal that I had tried to edit before giving it to my BH, he suspected the affair, and got a copy of the original (and I am grateful for that now, then I wasn't), I am using that to assist for dates, thoughts, feelings, ways to trigger additional memories that I didn't write about (its hard to not input what I currently feel though). Also adding to it details of each of my encounters to make a complete picture (what we have is disjointed)
I am being more transparent with my thoughts, more direct and to point - all because of the advice that has been posted for your benefit.
I am no way close to where I should be at 3 years out, and my BH is no where near starting the healing process, this is on me, not having done all of this sooner. There is an intense sense of urgency now. My BH cannot continue feeling like this. He needs a reason to continue with me or leave. I honestly don't know what else I can do...What I do know, this is what I needed to do 3 years ago and didn't, I don't know if you can make up for lost time...but I am grateful for every moment my BH is home with me, every time he walks in the door after work, every time he just talks to me. I know I can't mess this up. Time to pull up the 'big girl panties', and get to work, show him he is 'plan A'. If he choses to leave...well, I forced him to make that choice, because of my two affairs, but it doesn't mean that it would hurt any less.
So, I did say that I can be long winded, but from experience, if you want a future, start building trust, if it feels uncomfortable, if it feels wrong...then it probably is the right thing to do...so I am clear, when you are talking to your BH, not someone else...my BH coached me with this: just be blunt and straight to the point...I am taking that to heart...and it isn't always easy to do...
I hope that you and your BH find your way back to eachother.
