what i feel is.. hari was never married to that aatma.. maybe he was supposed to... maybe a childhood engagement or something.. but not marriage...
cuz in today's eiposdes.. when the brothers n baas r discussing.. anant says all that is happening is the same as 10 yrs ago.. rite now hari is 25.. so back then he must've been 15... so a past marriage is not possible..
also from today's episode we know that the mehsaani mangalsutr is the khaandani mangalsutr..... mayb the aatma loved hari.. or a child engagement or something.. n so she believes the mehsaani mangalsutr is hers.. as she was supposed to be the bahu...
another possibility is that kangna was his wife in his past life.. n his past life was also as a raghuvanshi.. which is why when he married her... she wore the mehsaani mangalsutr... which is now the khaandani mangalsutr...
the reason y i think hari wasnt married before in this life.. was cuz hari saying that he tied the mangalsutr on someone else.... was all under the influence of the aatma... hari going away from shri.... hari being pulled to bindiya.. is all under posession of the aatma..
the aatma made him say all this.. in order to break his n shri's relation.. but i dun think hari was actually married to that aatma...
cuz when he 'regained consciousness' n became normal in today's episode.. he told shree he doesnt knw why he feels like he tied the mangalsutr on some1 before... n why he feels like he is searching for someone.. the fact that hari doesnt remember being married.. probably means he wasn't married.. but the aatma is influencing him to feel all this... or even if he was.. it was in a past life... n now he's reborn as a raghuvanshi again.. so seeing the mangalsutr makes him go into these trances (cuz of the aatma).. but when he regains consciousness... he cant recall being married to anyone else.. as it was all from his past life..
n regarding what happened 10 yrs ago on ramnaomi.. i think that is linked to hari's dad's accident... the aatma was a past bahu of the raghuvanshi family... n wore the mehsaani mangalsutr... n now that hari is reborn in the same family.. she's been with hari since... to ensure he doesnt become anyone else's.. n 10 yrs ago.. something must have happened that caused the aatma to cause stuff in the raghuvanshi house (like she is now.. cuz of shree n hari's marriage.. something significant must've happened back then that threatened the aatma's right on hari).. which is why she caused probs in the house.. n on ramnaomi hari's dad had an accident n was paralysed...
