Re: In-law trouble - please advise
It seems the younger DIL lives with the in-laws.
The OP does not live with them and is the elder son’s wife.
Also, people know who to prey on and who not to mess with. The devrani seems to be a meeker, quiet sort who is easier to push around. The OP has probably been married longer, has two kids and an overall stronger relationship with her spouse since she doesn’t live with the in-laws. It would be impractical to mistreat her as they can’t brainwash their son by drilling his head 24/7.
This is why living with your spouse separately for at least a little while is important…
