Your post is so similar to my situation. We were married 26 years when my H had his A. My job was eliminated so him just leaving his job wasn't an choice...however when I got a new job, we moved and he got away from the work environment.
It has taken a long time and the roller coaster still continues. I actually made a post about
Spam a little bit ago. However, it does get better.
My first challenge that my IC helped me with was deciding if I was staying or going. For over a year, I had one foot in the marriage and one foot out ready to run at anytime. I too was waiting for him to hurt me again and was ready to bolt when it happened. He told me that I had to commit to one or the other...I couldn't do both. It took me a while to process that, but he was right. I was not healing by being on the fence. I finally decided that healing was a process and regardless of my decision, I would still have the pain to address. I decided to keep both feet in the marriage as we worked toward R. Although that didn't mean I couldn't/wouldn't leave if he betrayed me again.
We also did couples devotion during our transition in relocation. We were between councilors, obtaining insurance, etc. That helped a lot to have some dialog about the affair and marriage that wasn't planned, but guided by the devotion guide. It was hard, we cried...we finally got to a place that we had to stop however. It got to be painful BUT we were healing and didn't want to talk about it every day. For me that was healing also.
It has taken me years of watching him and his consistency to feel comfortable he was not betraying me. I took YEARS to feel comfortable with him even having lunch alone with his family or a family funeral (very extended family) which was in the area OW lived without me. I am ok with short times, but still get nervous with long periods of time.
I do love him, our marriage in some ways is better than it has been. There are some things I miss and will never come back, but I would have missed them regardless of staying or leaving. You might give yourself some timelines to re-evaluate your feelings. You are at 6 months out...try again at 1 year (if you feel comfortable waiting that long). How is he acting, is he consistent or is he slipping backwards. Is your relationship improving? How are your feelings at that time?
My husband has told me this year, that I seem like I am getting happy again. It has been 4 years....I would not have been happy alone either. Betrayal sucks.
