I dont think it has anything to do with Rashmi per se. Its about HIM. She questioned him. Questions him. Disagrees with him. Refuses to be his chamchi. Refuses to listen to his rude comments. How dare she reject him? He'd say the things he said about her..just about anyone who criticises him. He has self esteem issues. Gets offended easily. Even if she had lied about the methi in the paratha..he lied too. That he ate the burnt out. He didnt eat it..he threw it into the bin.
