Agree! She was craving for a family, which she got via the Deshmukhs. She doesn't want to be alone, so I think it's more fear than love that's keeping her there.
I would like the story to reveal if she knew the Deshmukhs before marriage. I get the impression her passion for saris was long before she became a bahu. If it was arranged marriage, then did they know about her via sari work?
Lots of gaps!
