Sis in law hates me for no reason?

So back then, my sis in law, which is also my husbands sis in law, we both were close. We'll txt here and there, and we both vent to each other. She tells me to talk to her and go to her if i ever need anything, or anyone to talk to.

A few mths after this, my husband and i were having problems. He was drinking at my sisters party, and acted out to me. My sisters were standing up for me, and she called the cops on him for yelling at my face, while i was holding our toddler. My husband does have a drinking problem, he gets aggressive when he drinks. Hes stopped drinking now.

Anyways, my husband told his bro, which is my sis in laws husband, to go pick him up. His bro then told their mother about this. After this happened, my sis in law just doesnt talk to me anymore. She distant herself.

I have another sis in law, and she told me that our sis in law, never liked any of my husbands ex gf after they have problems. Because she feels like its the womans fault.

I dont even know how to feel or do about this. What would u do?
