Boundaries with baby daddy

I need to mentally and emotionally detach myself from the father of my child. We were together for 10 years but it’s time I let him go, he’s toxic, he’s a narcissist and he had another girlfriend. He has left me multiple times and he has played with my emotions and now I ended up pregnant . He wants me to go to all my doctors appointments but I don’t want him to do so. I want him to stay as far away from me as possible during my pregnancy so I don’t get my emotions mixed up. In 9 months we can sit down and talk about custody and agreements but for now, for the health of my pregnancy I want him to stay the fuck away from me. He has hurt me in a way that I cannot even explain. How do I do this?
