I never realized how big of an epidemic this situation is becoming: 'unhappy' wives leaving their husbands. There are literally tens of thousands of articles, message board posts, podcasts, videos, etc of this exact thing. And yes, it's sometimes (but rarely) men that up and leave.
As Kind said, it's a guarantee that she is having an affair. Even if it's not physical (yet), it will be soon.
As hard as it is, now is not the time to reminisce about all the good times. You need to focus 100% of your thoughts and energy on you, and your direction moving forward. Fortunately you don't have kids together, so that will make things like 'no contact' a lot easier.
Stay strong and move forward with purpose.
