Sona loves to quarrel and argue with Dev and make him feel guilty.
She is also possessive in a way. She treats him as a thing than as a human being. Sub consciously she wants him to become hen pecked from a mamma's boy.
She manipulates him saying something like making him independent and takes away his independence and space.
She dont want to accept him for what he is. She wants to mother him and become his mother too. Only mothers talk of making their kids independent.
She is like her father, querulous. Dev made a wrong choice.
Sona is also a control freak.
She is so irritating.
