Bani betrayed by Jai,
Jai is jealous and insecure if Bani carries someone's child,says her sister that marriage without love is a compromise,also he doesnt want to share his love with Pia and Roshni(as he said he lost the former for good, this means he really needs Bani)but his ego isn't leaving him to confess,also Jai should break down and confess Bani,since Pia is more of danger to JB relnship so as Roshni. If Jai breaks down, Bani is safe in the Walia Mansion and she will enjoy her ownership of her husband and his wealth.Saying sorry to Bani is absolutely meaningless, nothing short of betraying Bani, except for the fact that she has his sindoor on her forehead and mangalsutra. Bani never asked Jai to be physical, although she wanted his love and a typical hubby-wife relnship, she never forced him to love her, it was only Jai's mistake on that night,he could have confessed his love before proceeding to the bold step, when Bani broke out, Jai was absolutely clear that BAni was insecure about Roshni-Jai relnship and adding to the wound Pia also.Jai should confess and Bani should stop giving sacrifices to the family where even her husband has no marriage ethics.Why the hell he feels jealous of Bani and starts boozing remembering all the sweet incidents(button stitching,tieing the dor, her hairs stuck to his button, etc), he loves her probably after the raaz is exposed, he will see to Bani's reaction and if she still accepts him then probably he might confess, coz he doesnt want to lose after gaining Bani, anyway i hope this happens fast before the Jig-Pia-Roshni damage Bani's life fully.
