I'm sorry, but IMO there are no success stories when it comes to infidelity. There's recovery and reconciliation and self-discovery, if that's what you're looking for.
Are my W and I a success story? Well, we're a statistic, how about that?. I had what most people want, a remorseful spouse that would do anything to make the marriage work. She saw her errors, immediately went into therapy to see why she needed this attention, and has been nothing but stellar. I got lucky. Had she said, "I want to leave you for OM", I probably wouldn't be here. I didn't make her go to therapy, she went willingly.
Things will never go back to normal. Our lives will never be the same, but they can be changed and improved upon. I personally do NOT want to go back to before, when I treated my W like crap, basically DARING her to cheat. Days when I sat on the couch, drinking bottle after bottle of wine, while she went out with friends. Giving her guilt for not being there for my mental health issues. I was a poster boy for self pity.
I am not that person now, and I will never go back to that horrid life. Her affair shocked me out of who I was. And shocked her as well, wondering how she got this way. How this bible studying good Christian woman decided to find refuge in another.
No one wins in infidelity. But people change. It helps when both spouses are on board.
For ME - I am no longer a blob that sits on the couch, drinking wine and filling my face full of crap. I run nearly every day now, lost a ton of weight and work every day on improving myself. I made myself attractive to ME, not just her.
I could go on, but I've got my own thread you can read.
