My biological mom has reached out to me

I am an adoptee. I was adopted at 3. When I was a baby my biological dad raped me and my mom let it happen. She didn't take me to the hospital when I was bleeding and almost died and said in court records that my dad shouldn't go to prison because while what he did was wrong he was gentle with me. Her right and my dad's rights were terminated. I have no memory of either of them. No memory of my assault but I am unable to have children because of the severe damage. My biological mom sent me a friend request on Facebook. I have trauma. Abandonment issues but at the same time I don't think it will be fixed by meeting or talking to her. I think it will just make things worse. Even if she apologized I don't really want that.i don't want her in my life. Am I wrong for not wanting to give her my time
