How n why ?

First of all revealing the truth that maya suffers from depression will make arjun more sympathetic n sensitive while dealling with maya .

2nd Any realtionship when starts with honesty n truth than it becomes more strong.

Saanjh never showed in her actions /words/thoughts that she is interested to get arjun back or want to separate him from maya till last episode.

she got trigger to investigate when she got alarming email, if anyone gets such emails n finds this facts. Obviously she/he will tell their frns.

If she wanted to use this fact for her advantage than she could easily told this vandana first, added masala /dramatised situation ( if required with media ) n created misunderstanding. Rather she chose to disclose all details to arjun.

Is this assumption made just because saanjh loved arjun n she can't be that saint/ selfless to do such things without selfish motive ? Than right no evidence to support such assumptions . After her confession she didn't get positive node from arjun when she asked him if he would have loved her back in same way if she had confessed b4 maya came in his life . After that she never claimed arjun's love as hers .

I don't think any doctor will reveal any patients details to strangers . Either it is filmy blooper or doctor is smart enough to hide major details.

Severe depression is not enough for ashwin to blackmail maya or make jhanvi stop from taking any legal action against ashwin.

I thought due to her janampatri defect ashwin consider maya as bad omen which had negative impact on her. It lead to psychological problem ( n i feel it is multiple psychological issues ) . Her constant anger outbreak could be reason that she was detained / n that she doesn't have any frns which ashwin used to his advantage. But besides that there should be some event that caused ashwin to become dark from greedy person, so much that he became inhuman to maya , so much that they tolerated his nonsense under some pressure.

If only depression is the reason , than story has lost its narrative somewhere.
