And, that's why Ishita compares him with Mani. I am liking Mani more than Raman. Mani may be boring, but he is the best husband material a woman would desire.
About your post, dear, many will say Raman was being Raman as usual. But, as Jay_bpm said in other posts, Ishita was also being Ishita. If Raman can be accepted the way he is, why not Ishita? If Raman expects her to change, what's wrong if Ishita expects him to change? Ishita's behavior at least doesn't hurt anyone and at the end of the day, all understand that she had good intentions and did good to people. But, what is about Raman's behavior...it doesn't do any good to anyone. Even his own brother doesn't like him for this reason. It's better he changes his ways to fix things, otherwise, there will be many more not liking him.
