Nothing unusual. In the beginning, MIL (at least most of them) like their daughter-in-laws and then they start to have problems. In my relatives the same happens. Every time a new bahu come, all sing praises until about a year and so when they start to hate her and all fights start. Misogyny make women turn one against one another. Same with Jaya, Aishwarya, Rani, etc. All have been victims of misogyny and have turned against one another in order to survive.
