Dealing with angry MIL

My MIL isn’t talking to me and my husband properly since 2 days .

Everything started like as of now I’m 7th months pregnant , me and my husband we stay in Bangalore and my MIL stays in Lucknow. We are in Lucknow to celebrate Diwali and will be staying here till the end of this month .

3 days back I told her about the return date and suddenly from the next day she started convincing me to stay with her till my delivery. I clearly told her that I want to go back with my husband as I need emotional support and also he has been with me from the very beginning of my pregnancy.

Also we have a very healthy lifestyle in Bangalore , with MIL I can’t maintain it as she has a habit of eating leftover meals, junk food most of the time ,too much sugar ,salt and oil in food , unhealthy sleeping habits, unorganised dirty rooms , hygiene issues and also everyday her friends or relatives visit her which is quite irritating . And we don’t intend to change her or her lifestyle because she has been living like this from a long time and my husband knows that I won’t be able to adjust in such environment.

All she started convincing me without my husband’s presence . When I told her that my husband won’t agree on her decision she said that she’ll talk to him . I was sure that he won’t agree and he did the same . He clearly told her that he won’t be leaving me alone with her and if she wants she can come to Bangalore a month prior to my delivery and stays with us.

This made her so angry and started behaving strange . She started arguing with my husband in which he said that he didn’t marry me for her entertainment in which she got more mad and isn’t talking to us properly. Now I don’t know how to handle this situation and make things smooth like before or just leave the things behind without getting bothered.
