aditi :
agreeing with all the points that you have raised, in fact i raised the same points in my own analysis of that episode ..megha once said to mohan, " mera aitbaar aaya bhi aur chala bhi gaya ", and she had been shown consistent with this character trait ever since. everytime something goes wrong, she blames mohan first irrespective of circumstances (except the riddhima fiasco) and the same happened here too. 12yrs back, megha's dilemma to reciprocate mohan's love was understandable coz as a widow she was bothered about social norms but now ? ab kis baat ki confusion hai ? even before marrying him, she knew how much mohan loved her kids. nanhi was her Spidey's fan but addu never liked him much ..and surprisingly, megha never took steps to bridge that gap even after 2yrs of marriage.
yes she was grief-stricken on losing her only son, but even then how could she say that marrying mohan was her mistake, he 's a wrong choice to be a father for her kids ? that was completely unacceptable. even normal couples say things like " mujhe tumse shaadi karni hi nahi chahiye thi " during petty fights , but when step-relations are involved, harsh words like this become blatant accusations shattering the person concerned even more. so yes, i would like to get a clearer picture of megha's stand point too, we need to know if she ever tried to find out where mohan is but gave up the search when she couldnt find him.
