I will be blasted for this but affairs are super complicated and so are people. It sucks, she broke you heart and mind and you had to do a ton of work to recover. You did great for yourself. You are the only one who knows what is best for you. I think you should keep your guard up and keep your mental health safe but if she is really remorse full and shows it then I would be open to talking. It take a lot of time for someone to wake up for the affair fog or limerence and then the guilt of it all has to be horrible for her. I read this book after my wife left me for her AP.
The art of falling in love.

I am moving on like you but I also don't think my wife is an evil villain but a broken person who made some really bad choices that will follow her for a very long time.
