I doubt Krish lacks flirting ability, he has bedded many women throughout the 3 parts, and all of them seemed to be impressed with his sexual ability. Compared to Desai he may lack a bit, but he is no slouch, that is the reason I believe that there is more to Meera and Desai than just great sex, she is mentally not able to enjoy herself with Krish. Krish may have pushed herself towards Desai but now he is not in control of the situation. How does Krish have a good personality, he cheated on Meera like it was nothing, and is yet to confess that. He is not a saint as well. He may be better than Desai, who is more ruthless, but Meera does not seem to care, she `had no problem with Desai forcing Nidhi.

So character flaws and personality may not matter much, also it seems Meera loves Desai's alpha and dominant personality.
