Mother In Law Issues?

I met my husband 3 years ago, we moved into together within 6 months of knowing each other, and married after 2 years together. right from the get go his mother hated me. He has stood up for me everytime she has said something, Lately it has become more of an issue, at the wedding she stated that she thought my husband would end up with someone other than me, and was rude to my family and friends I tried to put effort into getting to know her and getting along but she was just never intrested, she has told other members of there family lies about me and i know this because they have asked me about it. my husband stopped talking to his mum for about 4 months thinking things would change (they had a fight about the way she treats me) since they started talking again it is all the same, she tries to point out to my husband other woman and the good qualities they have. I tried to not let it bother me, but its gotten to the point where I simply dont understand or what i have done. i wonder am i really that bad of a person? when i look at my husbands brother, every time he has a new girlfriend or relationship all you hear about from the MIL is how wonderful his new gf is or the things they are doing. She isnt intrested in the things we are doing, I have had troubles conceving children and she turned around and asked infront of me , if she cant give you kids "why would you marry her" i was mortified and heartbroken, She has told everyone that i try to control my husband, which is untrue he is a grown man and i have told him to make his own decisons if he wants to go see her/talk to her anything to atleast let me know, so i dont worry about where he is, if he is around them and i am not there, i dont call or text him simply because i know they will say something I try to not go around to her house, or have little contact with her as i dont want to put myself through that and my husband is fine with that, I go to all the other family things, and i am quiet close with his cousins and aunties they love me, But his mother, step father, brother, and step siblings, just cant seem to take the time to get to know me and they simply Hate me, I dont get it and i dont know what i can do
