At that time, he was so scared of losing G, he felt its best to get an official marriage certificate and then "face" his family that too he did under G's insistence.
The problem he J faces now is that HE realizes how much he misses his family members (even if they want nothing to do with him and his new wife); its hard to reject the emotions of mom, dad, uncle, aunt, grandma once they are in FRONT of YOUR FACE.
This is why he kept "lying" to G about tickets to Mumbai, he had high hopes that if he and G hang out at haveli for some more time, just maybe someone in the family will melt towards them; he just didn't want to leave his family estranged, he was hoping that if anyone showed cracks of acceptance ---time will take care of the rest.
But now with the sudden reveal that J and G's nuptials are illegal, does J have the GUTS to ASK for a divorce.
He is and has always been a coward, that's why he LIES all the time for even the smallest things.
Will Dadisa allow divorce? She will invoke haveli izzat --taking a 2nd aurat is ALSO bad and society takes care of that by shunning the souten but a divorce is the ultimate urban evil.
Can't imagine Dadisa taking it too easy.
And what about Jagya, is he really ready to be rid of Anandi (FINAL AND FOREVER?) Considering him and his new wife are not exactly cuddling their nights away trying to console each other --J and one side and G on the other side of the bed.
And G will she have a change of heart? Knowing now what she didn't know before.
Or will she make the same mistake 3rd time?
