I would like to mention here that Bani's "feelings" are ambiguous because of poor writing, not poor acting. She is very much in love with her husband, because makers will not go into so much depth of trying to differentiate between attraction and love. It's ITV and the show is finite. That should have been done before.
This constant hot and cold behavior can easily be explained as the turmoil within Bani to stick to her Nagvanshi duties or give a chance to this marriage. Jai's constant nagging can easily result in an outburst from Bani to put him in his place and not remind her of a "soul connection" which he never respected in the first place.
Frankly, time has run out to establish "love" from Bani's part. You cannot spend 4 months to establish a heroine and her love. It's ridiculous. They need to stop this Bani's teasing game and show her maturity to accept her love and marriage, because otherwise she will be at a loss.
Married couples have issues even after they fall in love. And if they don't show the strength of love here, then they will run out of time to show other things which conveniently are on hold, thanks to the null VAni equation. Other Naagin series couples also had issues after they fell in love, but they handled it right. So that needs to happen here as well.
Jai-Shukla, Teer, Monil, these too need to see the light of the day, these people seem to have forgotten all of it, like it never happened.
