Welcome to the forum!
But I beg to differ..
I don't think Vansh character is getting destroyed..
Vansh is still not madly in love with Ridhhu..he has to trust her completely before that..coz the basic foundation of a relationship is trust..
Yes Vansh has an attraction for Ridhhu,a soft corner for her or began to understand her...but he has a long way to go before he starts trusting Ridhhima blindly or start loving her madly
In that process..he can doubt her(because Ridhhima is still in contact with her ex BF and still on a mission) its ok...It will go on till he trust her completely
Vansh has feelings for Ridhhima..but he is still a "grey" hero..He might have started feeling for Ridhhima..but that doesn't mean his sixth sense or brains stops working..
And I have understood the writers..With the progression of the story,all the shades of Vansh will be out..which will be a mixture of positive and negative shades
And regarding Anupriya,I m damn sure one day he'll trap her very nicely!
