He suspected his wife when there was no basis. NOw he knows that in a month Bani will be back with Jai. HE is scared as Jai told him off today. In this panic state he is desperate.
HE can do whatever after one month JB will be together.
I think Bani is going to ditch him again on Monday. She will go to the picnic with kids & Walias instead of Tanu's party. There is no way she will refuse her kids.
SHe was so uncomfortable with him today. She doesn't think of him as future husband but someone she is obliged to.
