My Mother-Inlaw wants to pull my family apart

I have a terrible relationship with my mother-in-law and I don’t have a clue how to make it better. The woman hates me. I think she’s angry because my husband married me instead of a family friend she adored. She is constantly finding ways to pull us apart, and she’s made it clear that I’m not welcome in her house. We have a 4-year-old daughter, and when my husband takes her to visit his family, I stay home. Whats your advise
