I too feel very bad for Jay. Like you said, he is a decent man and wants to make his wife happy. He normally is not a playboy, but he made one mistake during the weakest moments of his life and now the poor guy is suffering badly for the guilt. If I were Bani, I would forgive him and give him another chance, but it all would've been easier for Bani if he came out clean by admitting all this as soon as it happened. The same night they both could've explained the situation to Bani and begged for her forgiveness.
