Hoping i have a miscarriage 😞

I don’t want to have this 2nd baby I’m praying i lose it or have a miscarriage i hate the man I’m with he’s mentally and physically abusive and i can’t stand him i have no where else to live or go i have no car or nothing i was recently staying in the homeless shelter with my 1 year old daughter and left because my stay was up. I’m currently living with a friend who is married but i know that won’t last long. This pregnancy is taking a toll on my daily life and function i hate the fact that I’m pregnant again.... does a father have a say so in adoption? I really don’t need another child. I feel so bad but i just don’t need more stress.... help
