There are many people married and not living together,what about people who work overseas for 6 months at the time?
My advice,do not create a problem out of nothing.
Let sleeping dogs lie.
If you and your wife agree to a lat relation and you are both happy with that then who
really cares what others think?
Personally i know of more then one couple who do not live together anymore
but every year they both go to immigration in other for the husband to get another extension.
Is it breaking the law?Maybe so but so is speeding but as long as you don't get caught?
I know of much worse things.
