Welcome to the forum kukuraja!!
This is a very nice post on the analysis of Radhika's psychology. I completely agree with you.
My take on this topic is:
Rads always got her Dad's unconditional love but never got the same from her mom (Devki). She always felt the love she gets from Devki(whatever she got) is more precious to her than anything else in this world.
I agree she can live with "Dev's hatred" but not with "Devki's hatred".
She never longed for "Dev's love" as she had always thought that "it is impossible for her to get Dev's love for real in her life", yes, she loves him and wants him to be happy while being bound within the social and family rules but, don't have more clear expectations from him.
Where as, she had always longed for "Devki's love" and had always valued "Devki's love as the most precious gilf t of God" to her. She can't lose that gift at any cost, not even for Dev😭.
That's why we all hate Devki so much. Devki knows Rads weaknesses, strengths, desires and priorities very well but never cared to thrive for providing them (especially like a mother, not like another woman who is sympathetic to an orphan)😡😡😡.
The day Radhika completely unshakles herself from the moh-maya of this love and longing for love in her life, I dread that she may really detach herself from everyone (as she is so much tired of keeping everyone happy and making everything right in her both families) and take sanyas whole heartedly (don't throw eggs or tomatoes at me, I feel that is a possibility based on this psycho-analysis), I myself don't want the story to head in that dubious direction😕.
Hence, It is very critical now that Dev and Shastriji to know the magnanimous truth of Radhika's marriage as soon as possible (that too with a confession from Devki).
