welll we must know shiv's psychology... slaps will make him more angryr.. or probbly sulky.. he is choti munda trapped in a man body. he is sensitive n needs attention. smacking or slapping him will not help. i hope gauri's motherly love n maturity will defeat his childish behaviour. đ. he really needs her coz she is genuine n kind hearted.
though he deserve one.. but you are right slapping will make shiv more angry and he will hate gauri even more
