You've down the right thing Op. He is a sex offender. A rapist. He knows he's doing wrong and he tries to convince you that you're imagining it / over-reacting because otherwise he needs you to believe that. He knows that otherwise you could tell people or report his crimes.
You are doing 100% the right thing. You are telling the truth. He is a rapist and the Police should be told.
But aside from what the Police do, and how long that process takes, you need to be thinking about what happens next. Clearly you don't want to be with him anymore. He rapes you, affects your mental health, lies, gaslights, doesn't respect or love you (you don't do those things to someone you love). He doesn't deserve you. He doesn't deserve the love of your daughter.
Imagine as an adult that you told your DD what he was really like, and that you stayed for her. She would be mortified that you continued being sexually assualted for her.
Stay strong. You've done the right thing. Keep your resolve and you can get away from this vile man and his despicable behaviour for good. A better, calmer, happier and more contented life awaits you. You have to get through this bumpy bit, and there is support for you through that.
