I'm not telling my family

My side of the family is the closest to to me right now, however they're also the most toxic. I've been wanting to actually cut them out for a while now. They've been using my previous marriage and my son as a hold over me. They refuse to acknowledge my partner, wont call me by my name (Im in the process of changing it).

When I gave birth last, my mother tried to tear me apart by suggesting that my abusive ex was the best for me and I should leave my current partner for him. She told me when I found out I was pregnant to give up my child.

Most of my family follows her lead.

I cant deal with them. I need a stress free pregnancy for the first time.
