the problem is both RiAnsh started loving each other without any foundation of understanding, trust, faith and many important things that are basic in any relationship. Vansh damanded riddhu's trust on him but never trusted her as a wife and when he did it was really late. Riddhu wanted vansh to be a saint just like her and made impulsive decisions.yeah actually..point is vansh never understood riddhima from start and then believed and trusted her but she hid many things from him so now as Vihaan he is trying to understand her,who is real riddhima and what was her reasons to do those things before and now which is good in a way as he is not making judgements but trying to figure out.
But this all figuring is taking a toll on riddhima as we can see, but vansh/vihaan have no idea becoz he don't know her story.
So its their relationship,it was complicated so we can't tag a person wrong and blame them.
They both are wrong at places and both are right at places.
Now we to see how cvs handle this track as it has great scope but good thing is they are focusing on it.π
