I am not sure of Arup ji's marital status. If he has already obtained a divorce, he can have live in relation with someone who also is not already married....
Though it is Arup ji's personal matter, I think many people may get into the false beleif that having live in relationship is OK while divorce matter is still pending in the court, or after one has deserted one's spouse. Hence in my opinion, such misleading advice should be avoided in a forum which dedicates itself to lawyers.
