Gentlemen, how would you react if you saw your wife/gf having sex with another man?

I've been married to a Chubby Soulmate wife whom I really love for 2 years. We were happily living together and having amazing times together and my wife kept doing everything I wanted her to do. She always wore what I wanted her to wear and never said no to any of the dinning options I have been giving her and always doing what I wanted her to do.<br><br>However, 3 weeks ago, when I was on business trip, I happened to go back home and when I walked into our apartment I saw our living room had been messed up and everything was dropped over the place including chairs and tables. I was in complete shock and was wondering if our home got robbed or something but my wife was nowhere to be found and I noticed that the place smelled like the hell. I checked all the rooms and no one was there. When I headed to our master bedroom I couldn't believe my eyes. My wife, whom I loved more than my life itself, was having sex with another man who was bigger than me. I'm a 5'8 skinny Asian dude and I thought I had nothing to offer my wife. My mind was completely destroyed and I rushed to my car and drove away and never have been back to my hometown and never have seen my wife and never talked to her again. I couldn't sleep and couldn't eat anything ever since. I'm a total wreck and I don't know what to do really.
