She is trying to outsmart her hu*****and. But actually she is ruining the foundation of the marriage, the mutual trust. I believe that most hu*****ands would be determined to look for a new one after back to china and divorce right away after he finds the right one unless this hu*****and is a chicken. It is a nightmare to sleep someone who is playing tricks on you for the most important issues.
Life is a gamble. Sometimes you must admit that there are something you cannot control and need to pretend to be stupid. 傻人才會有傻福!
