I can honestly attest my WW and I are at the best we have ever been, as we come up on our 20th anniversary, but it was a long road of pain, regaining trust, recommitment, and forgiveness. It takes time, and I hope for you it will just be a matter of being patient and giving it time.
After DD#4, which was the last one, something changed in my feelings for WW. I did not feel the same amount of love for her as I had before, and it felt terrible. We had just moved into our dream home only 9 days before, and I told WW I wanted a fresh start after the madness of the previous months, and what I discovered on her phone that night was such a huge betrayal. I was also overwhelmed by the mind movies and triggers, and it was all too much. But I stayed. I had already promised her after I walked out on my family on DD#3, one of the worst nights of my life (though I came back soon after), that I was going to try to make our marriage work if she would.
Thankfully, my love for WW came rushing back a few months later, I am not really sure why. I think it was partly her showing me I could begin to trust her again, as her wayward behavior totally stopped, partly a lot of deep conversations in which she was willing to answer all my questions honestly and openly. I even admitted to her how my love for her decreased for a time, and she thankfully totally understood and was not very upset.
But it took a long time, about 14 months, for my trust of her to once again reach 100%. I decided that if I cannot trust my wife 100%, who can I trust in this world? When my trust for her was less than 100%, I asked my therapist if our marriage could succeed if I felt less than 100% for her, and she said it could, but it just still felt wrong. But I finally got there, as my wife proved to me I could trust her again, that her wayward behavior had totally stopped, and for good. She has repeatedly assured me it will never happen again. She recognizes how it destroyed me, our kids, and her. She is putting the proper boundaries in place now (she has had a cop and two men at stores hit on her or ask her out since, and she rejected them all). I was happy to announce to her the night before she had to travel across the country with one of our daughters that I trusted her 100% again, and it was a powerful moment for both of us.
I know that that person who was cheating on me was not my wife. She was struggling with something that I would liken to a drug or alcohol addiction. She told me it was all about the attention she was getting from other men (two were co-workers, the rest were online). She was acting very impulsively, which is likely a symptom of her ADHD, and she just could not stop. I knew that if she could just stop her behavior and I could get her back, we could succeed. I also realized that I needed to be a better husband to her. She said she felt I was pushing her away, which I did not do intentionally, but that was how she felt. So I have taken the measures needed to avoid doing that again.
We had to recommit to each other to bring that joy back to our marriage. Now a bit over 2 years from DD#4, I am so proud of my wife. She has had major promotions at work (including a new one coming this week), we are living in our dream house that we worked very hard to get, we are at the best we have ever been financially, and our children are all thriving. I would have made a huge mistake leaving her, even though I came very close. I wanted to give her a chance to change. I would have been miserable without her in my life, because when things are good for us, like they are now, they are so good! I am very proud of us and how far we have come!
Good luck to you! I hope you will one day be able to celebrate your anniversary like you used to again. I recommend individual counseling and couples counseling if you are able. We did all of that, and I know for me it was essential to help me recover. There is hope for you!
