There is no contradiction in her character, my friend. The story since part I has always shown her as a manipulator and selfish with no heart. It always showed Krish has a good heart but is slave to his fantasies and submissive, due to which he gets used by his wife. Meera never took any responsibility of anything, not in the last chapter, not before. She always accused Krish of everything since beginning.

If Krish has used Meera for his fantasies is a fact and can still be good at heart and can love Meera then Meera manipulating Krish is not manipulation and being selfish and she can also love Krish despite cheating him many times on her own account , cannot attribute one as innocent and other as schemer just because we do not know her pov.
Only this episode proved so far that Meera is living in guilt and was not part of Krish's games willingly and also accepted Desai's love hence the contradictions until then every thing was part of couple's plans so i cannot decide if Meera is like this from beginning at least for me no proof or her actions suggest otherwise anywhere before Desai came into the picture.
