Yes, but this can be the stepping stone no. With whatever Kabir is planning, his manipulation, instigation, everything will act like a stepping stone and then R's parents truth - probably the final blow or if IShani does something to hurt the baby or anything can happen. The writers can use this as a medium to show the separation track - stepping stone or maybe not wanting a child (choice between husband vs baby), anything can happen.
Separation can happen with baby and without baby
Either knowing Vansh forgive Ishani after all she harms baby then yes she won’t forgive Vansh
If he stands on his side for whatever reasons she will leave for sake of being mother
So can see two separation track if they come with us but need to see which they choose
