Dear OP,
I'm linking to an article by Melanie Tonia Evans: blog.melanietoniaevans.com/how-to-show-up-in-life-to-best-support-yourself-and-others/ and you may wonder why it is applicable to you - but if I tell you I have been single since 2012, you probably feel sorry for me being alone. Except I'm not. I'm living a full and happy life, full of love from friends and family. That is down to healing my need for external validation, and that is one of many things this article talks about. Her writings on self-partnering explain this much more. She has lots of free resources available, including YouTube videos, blog posts, a free course etc.
I dump men who do not make my life better, the minute they stop making it better. The notion that I would write 'my relationship is crippling me' at the 6 month mark is almost unimaginable - because if a relationship is so hard, so fast, it's an easy leave.
But I remember being where you are. So desperate for love that I had no boundaries, and a sociopath fast-forwarding and love-bombing felt like water in a desert. But that is dependency, not love. I stayed with him for 6 years of all sorts of abuse, and by the end I was a shadow of myself. Someone earlier said they wished he'd hit you so that you would see. But I can tell you it doesn't work like that. By the time he hits you, you will already have well-rehearsed reasons for why it isn't abuse. Like the one you already have.
It's a bit of a cliche, but it is true - if it hurts, it isn't love.
He is a severely disordered man, and in order to put up with his abuse you are twisting yourself into a pretzel in a way that a healthy person just wouldn't.
Healing starts when you go No contact with him. Please, if only for your daughter's sake, do that today.
