My poor child

We have a son that is two years old. My husband has 6 teenager kids from previous marriage. The ex wife do not want his kids to visit him because of me.

She control their grandkids (one girl 1yr old and a two months boy) like also not to visit my husband.

The kids ONLY want my son to go their house all the time. They do not want visit my husband or go out with me as family, only my husband can go with them. Felt humiliated??

One day I went drop my husband and he went inside then his daughter wanted to take my son inside the house without telling me if okay like permision and told her no and she got super mad and call me beep lady. I told her that she should visit her dad and my son whenever she want but she got mad. The kids tell my husband to leave me for to share custody of my son. How can they be so cruel. My husband listen to them because is his kids. My poor child do not know the way they are cause he is 2 years old and have no proof.

Any advices?
