i dont think anything will stop him anymore.On the contrary i think he wants hamna to speak up the truth to her hubby.His revenge is simply that she couldnt speak up about them before so he now wants her to admit their relation.He wants to bring her into the breaking point where she actually blurts out the truth.
What will he gain by doing so?
What does he think Azeem will dump her? Yes he will be angry at her at first for not trusting him enough to tell him her troubles but when she tells him the entire truth about how you have been troubling her he will understand her as past is past.
