Priya's fault is her self sacrificing nature and her taking that one big unilateral decision as a result which we all find difficult to digest ...
Ram's fault is his anger overruling everything in the heat of the moment which mars his ability to think logically and maturely - infact this combined with his arrogance as 'the ram kapoor' as he himself admitted while tracing his likeness with pihu makes things much worse...and the serial is replete with such instances in the past ...
so priya suffers and is criticised for her mistake arising out of a character trait, why shouldnt Ram's mistakes arising out of his character traits be criticised too ? ...
Yes he is hurt and ssuffering and his anger is legitimate...but the circumstances under which priya took that decision brought a lot of hurt and suffering on her too...this blind rage where you are so hurt you dont see that the person was not disloyal to you, she did not go away with someone else , she did it out of love for you is problematic...not forgiving her so soon, being rude and angry is still understandable, but suddenly after 5 years going all out for custody of a daughter he had no knowledge of for 5 years is idiotic...a 40 year old man would know its serious repercussions on the child's life...but ram kapoor is too blind right now to see that in his urge to hurt, lash back, hit back...
