I am sorry for all you have been through and are going through.
It hurts to stand up for oneself and to be excluded because of it.
My BIL is a bully and is very abusive. He has tried it with me, although it took him years to actually try his imposing his bullying upon me. He is very immature. He has beaten my sister when he's angry. Yet, when I report how he is abusing me, I am banned from seeing my sister and my niece and nephew -- until I recant. I won't be recanting. I may miss some of the family, yet I do not agree to allow him to continue to abuse me.
I hope your family sees the light, sooner rather than later.
My heart goes out to you.
