Hey OP, Let me list it down. Don't listen to teenagers here who have no experience in arranged marriage and how it works. Most of the jokers here are living in la la livein relatioships/love marriage is wonderful blah blah. None of this is going to help you since you are in arranged marriage.

The number one thing you need to get done is to delink her from her mom for every private thing that happens in your home. That is of paramount importance. It was easy in the olden days. Now with phone it is very very difficult. Earlier, roles were clearly separated between man and woman. Now it is not like that. Give equal space and expects reciprocity. First step is to stop involving your parents in everything. It may not appear to you that you are involving but you might be and the girl can notice it. Now.

1) If required, move out nearby if you can -> Make sure to pay your parents a visit every day - it will eat you if you are not there to take care of them

2) After sometime start telling her that she does not need to involve her mom in everything and it is your life (both of yours).

Just do the above 2 and you are done. Mother-in-laws nosing into your life can screw it up. Show your authority over your family. It is your family at the end of the day. Neither your parents or her parents will come and fix things up magically.
