I will mirror what RR said, it is never too late. I'm in the same boat as you, i have days where i feel hopeless and I'm consumed by my emotions, other days i go about my business and have no thoughts on my wife. Focus on yourself, get into the best shape of your life, get out with friends, improve yourself at work! Anything but focusing on your W.
You didn't mention any kids, going DARK/NC should be easier for you. Here's the thing sometimes we forget, our wives did not fall in love with us overnight, and they didn't fall out of love from one day to the next! It will take time for them to see any changes and actually believe them. We cannot control them, Be the best Ste7e you can be, if recon happens great! If not, her loss and something better will come along at the right time. Stay strong
