it has been more than 5 months
you are still struggling with your crush? Why don't you just tell your boss you want to have an affair with him and see what he thinks. It would be much easier on you than come here for help.
The truth is that if you boss is really attracted to you he has already tried to get into your pants. However I think he needs your professional help more than a romantic relationship.
Go back home to take care your kids and your hu*****and.
Feel sorry for your Chinese hu*****and.
