If he himself was going to marry Tia what's his problem what's Anika's doing.
In today episode it was crystal clear that what he's doing is out of anger, revenge because of his thought that Anika spent a night with Daksh.
Where's his problem in this when he himself was preparing his wedding with Tia??
Hope viewers don't fed up with Tia story as she's coming back??
Shivaay the super powerful mighty businessman he believes himself to be can't find out the truth about Tia??
Your points.
