I would disagree.
I think he is an abuser.
Op you can fuck your life up over this disordered individual, or see him for what he is (regardless of what people who don't know him well think of him, that means nothing, people thought Ted Bundy was a nice, normal young man) and move on and enjoy your child and try to minimise the damage and stress he causes you from now on.
Obsessing over sociopath, disordered individuals leaves women in the position that eg Whitney Houston ended up. Or women I see sitting on the street with a bottle, talking to themselves.
Get some self belief, some skepticism (about him), some indifference and don't fixate on how he could treat you like this. He treated pretty much every other partner like this too, by the sounds of it. And also people have had worse done to them. Every day on here tbh there is as bad or worse behaviour to normal, nice women.
You can only weep and wail and analyse for only so long, and then you have to move on and shrug your shoulders, and focus on looking after yourself and doing the best for yourself.
You have a little person to look after as well as yourself now. You two can have a nice life and you can meet someone well adjusted - which he is not - in time if you want.
The amount of your time (even if it's just thinking about him) this specimen wastes of yours, from now on, is entirely up to you.
