Amazing! One of my wife's friends got a divorce due to a Chinese mistress. There are so many stories of married Taiwanese men  going to work in China, and getting a mistress and some actually starting a 2nd family - while having a US family.

A big reason for this is when your running a business, you need to be willling to take risk and have great self esteem. The danger is you start believing in yourself too much. I refer to it as the flying to close to the sun (Icarus) syndrome. I have seen many families badly damaged when mistressses break up a family.
