What goes on/ went wrong between two people in marriage - nobody knows..so purely to bash Sadaf vis a vis Syra "on looks" is wrong.
What is immoral is if Shehroz cheated on Syra while they were married, with Sadaf..and then openly lied about it as well. Syra has shown grace and dignity by not speaking up about this on public platform..its unfortunate that Shehroz Syra parted ways..but then its better to live happily separately than be stuck in a bad marriage.
