1st Phase-
Falling in love with Arjun, and trying to make him love her back
(The proposals, Maya's revelation about her past and gaining respect from Arjun, Arjun reciprocating her love)
2nd Phase-
Marriage Phase
Will be encased with possessiveness, obsession and control
She will want to keep Arjun close to her at all times, and as Jenny said she will only love Arjun in this phase. Meaning that she will love Arjun more than anything, and would want to be near him at all times.
3rd Phase
first Guess- is that it could be her healing phase
Arjun has vowed to never leave her hand at any time, and if he fulfills this promise, then he will stand by her at all times... he might try to heal her through love and patience... he might find out that Maya's mental condition is not sound, but that might not cause him to leave her.
Second guess- Arjun's true intentions and revealed and Maya takes revenge from him
Third guess- Maya leaves Arjun (seems impossible) and tells him to move on in life, and gets herself treated. Arjun and Saanjh come together...
The story is subject to change, and these are only my predictions
But I hope that her last phase is the phase of her healing
She deserves love after all that torture and pain she has been through
She is literally like a scared child begging for love! I can't see her begging like that anymore, especially in haldi scene when she said to Arjun that she doesn't want to go back to a colorless life! That was just heartbreaking
