Leaving his mom

Yep, exactly.... if you've married a decent, sane, educated and mature lady who isn't fake and doesn't have unnecessary nakhraas, she won't have any problems following your wishes.

You know things do happen between bahu and mother-in-law, and living together, they will happen..... but bahus don't have to fight like uneducated jaahil females. They should keep their mouths shut and resolve the issue through the husband, not by complaining but through open communication and talking it out. Secondly, mothers who are secure about their children do not unnecessarily pick fights with their bahus, so it also depends on the mother-son relationship.
