Sure they BOTH make mistakes...but the sad fact of the writing of this show is that only MOHAN admits to his mistakes...Megha will HARDLY ever admit to her mistakes...and there's a HUGE list of mistakes she's racked up...jumping into marriage with Mohan when Addu wasn't ready for it...post marriage, NOT tackling the Mohan-Addu dynamic with more concern rather being busy with her own god knows what issues...They've steadily and consistently made her a very self-absorbed character.
Time and again, Mohan DOES makes mistakes...but the amazingly disarming part about his portion of nazams is that he still ADMITS his mistakes...loves her unconditionally despite anything and everything...while Megha's "love" for some reason always seems more conditional and surprisingly immature.
Yes, Mohan is a man-child...he never denied it...was forthright about it since day one...but what is Megha? A mother of two...a widow from such a young age...you'd think she'd have more maturity and samajh, more RESPONSIBILITY towards her kids...but I guess not...no thanks to the lovely writing of the show as always...her #1 priority should have been her kids...but she messed up BIG time on that front...and now Mohan is an easy scapegoat for her losses...
This is what i too said in another thread. Mohan makes mistakes but admits to his shortcomings and tries to make amends.. We never see this from Megha's side. She conveniently puts the blame wholly on mohan. We never see any introspection in her. Just blame mohan for whatever happens in her life.
