Niharika ex husband???

Hi guys 3 days ago i started watching this show and binge watched all the episodes .

So since i binge watched so i think i missed something i need some answers

Where is Niharika ex husband father of ayesha 

Did i missed or they didn't mention.

Because i remember VBK saying that niharika was also married and had a child when he met her.

Can some body explain to me about him? Where he is or Makers didn't mention it.?

I don’t think makers have mentioned his whereabouts

Ok 

I hope we also see him otherwise aise hi mention karne ka faida nahi tha 

Aur question.raise hote hain k woh apni beti ko chorr kar kahan ghum raha hai?
