There is a reason you are with a man that thinks he can hit women.
MIt's because you were raised by one.
It's no accident that we fall into these things, we are prepared somehow by our childhood.
A NORMAL parent would want to tear the fucking head off anyone that hurt their child.
A NORMAL parent, not a super human one.
You may work through this with your H, you may not, but know that NOTHING you EVER did made him hit you. HE CHOSE TO HIT YOU. Active choice to do so.
No-one has that right. Anyone who agrees with him, in the cold hard light of day needs to be shunted off to the sidelines so that they don't do you anymore psychological harm.
Your eyes are open now, you can't trust your dad. I would be surprised if your H earned his trust back either, but if he tries hard enough, it's possible. It may be that you NEVER regain that trust in him.
No woman is EVER wrong for leaving a man that hits her. No person should stay with someone who uses violence as a method of control against them.
This was not your fault lovey, none of it.
May I suggest that you read Lundy Bancroft's Why Does He Do That? It might help
