Unless the story takes an unexpected U-turn again scenario 4 is the most probable scenario. She now trusts Desai more than anyone else in the world. There were multiple instances in the last episode that confirms that -

1. She mentions to  Krish "nothing about Desai will make her hate him".

2. She trusted Desai about Ananya (who was known to be her best friend until the second chapter).

3. She now prefers to go out with Desai than her husband, she decided not to accompany her husband to drive and preferred to stay back with Desai.

4. The only place she asks Krish to accompany her is the temple because Desai has no interest in going to the temple.

As somebody else mentioned in the thread - in the initial phase of an affair/love person is blinded by the hormones and trusts the other person completely.

I wantedly left 4 as a possible outcome because to make 4 possible, Desai and Meera have to act a lot in recent episodes and the difficulty of doing that is not as simple as you think it is, esp major thing that go against 4 is them knowing about holes in the door and recording..I doubt they know it..May be Desai do but Meera highly unlikely.
