Jagya throughout has been a man who realizes the value of the doll he owns only after he loses it!!!
Anandhi was his first doll and he made her do his home work etc even as little kid and once they were separated...he fell for her...
Soon Anandhi came back and then he lost its value then there was Gauri...though Gauri fell for him long back...he realized his love only when she went to meet another guy as prospective groom!!!
And as for Anandi, i feel he did not love Anandi even now but was bawling in his self pity of having lost his family and wife when Gauri cheated him...but when he realized that Anandi was going to be someone else's he realized his great love for her and wanted her back!!!
So even now his realizing his his love Ganga is because he is about to lose her!!!!
As for Saachi i feel he did not even feel friendship towards her...it was just his duty bound nature of wanting to respect the family to which Anandi was married and his wanting to respect his families whims and fantasies...
the mistake of match between Sanchi and Jagya goes wholly to Shekars esp the Dadu and Ira...who didn't even think whether her daughter in law ex husband will be good
and without doubt the blame falls equally on Dadi sa and Sumitra the great senseless mother who wants young bride for her spoilt rotten doctor son is ideal...
why can't seh open her mind a bit and think of marrying Jagya off to some widow or divorcee...what the hell is wrong with that!!!
