Dont give it the slightest worry Mike.....My Mother in Law feels the same about me !!, but my Father in Law is a treasure and we get on extremely well.
When in China, Ming, ( and Jessica) must by neccesity pay all the correct attention to Mother that their culture demands. So while you are there, Jessica walks a tightrope !!!
But once she is in US, all will be well.
You see, Jessica has already made her decision fo her long term future happiness....and you got the prize....nothing can change that.
This interim phase is just that...interim.
We are now looking forward to Ming's Dad's visit to Aus in July...but Mother refuses to come. Dad says he dont care, he is coming anyway !!!
Dont sweat the small stuff
