Let her be selfish and concentrate on her son. At least, by this way, she may leave Anandi in peace and get close to the Sekhar.
Anyway, practically, it is quite unreasonable for Anandi to be close to Singh at the end of the day it is her ex sasural, if she keeps on always prioritising them, then this will create more controversy and now jagya is back. As Bhairon said Anandi and Shiv may be clean in their mind, but what about other people. Anandi who always takes her mayka as less priority should follow the same example with Singh. Only with Singh, she is a bit over sensitive because there is an obligation.
Now BV should show Anandi flowing away with her in laws, and Singh reviving j's life in all ways.
