<human>: I started dating my boyfriend in 2014. I already had a daughter (1F) when we met and he stepped into the role of father since hers is absent from her life completely. 

In the time that we dated, my daughter got VERY close to his family especially his parents who love her dearly. 

My boyfriend and I went through some rough times and separated. Basically, he started mistreating me and we fought a lot and were both unhappy. 

His mother is the issue now. She HATES me. She has a weird attachment to her son and sees him as a god among men and thinks that I made him unhappy, and for this reason, she vilifies me. She has told me to my face since we broke up that he deserves someone better. 

Although we broke up officially 10 months ago, I have continued to allow his entire family to see my daughter as often as they want. We are cordial, but I know his mother does not like me or respect me. She is extremely over dramatic in general and passive aggressive towards me. Because she is so passive aggressive my boyfriend doesnt really see/notice when she does stuff and it's easier for her to deny it. He doesn't want to rock the boat but I cant live like this.

My boyfriend and I have recently reconciled and have sought counselling to work through our issues. It seems our last hurdle is telling his mother. He has promised to stand with me and be on my side but we are  both struggling with how to deal with the situation. I don't know what more I could do to make this woman like me. I have jumped through every hoop and because of my anxiety I cant stand being at their home for holidays and such which my daughter really loves to do. 

What can we do/say to stand up to her?

Provide a brief overview of the text.
