Thanks for your replies!

We have spoken to the ex. She is well aware of my MIL behavior. It seems spiteful that she continues allow my step daughter to spend time with her.

2 weeks ago, I was my MIL's target. I am the devil, the worst thing her son did was marry me, I am a piece of s**t , she called me Ms. Education repeatedly (like it is a bad thing) etc etc. This was said at the lunch table with my step daughter sitting on my MILs lap. My husband told his mother that is completely untrue and she disgusts him and we left. My husband has cut off all contact with his mother. We used to attend a weekly family lunch at his Grandmothers home. But have made alternate arrangements to see the rest of the family without incident.

It hurts me because I have tried to be kind and respectful to my MIL because she is my husbands mother. Despite my own feelings towards her. I have been upset since, because I don't know what I have done to her. My husband and I have only been married since April and are very happy. We bought a home and our life together is amazing.

It hurts me that my father in law sits by with out defending his son or me. Or protecting his granddaughter! The family all allows my mother in law to behave this way without consequence.

I have a loving supportive family, they would never sit by....

Any advice?
