Ok here's the thing about abuse. first off it's not emotional abuse as you stated, it is physical violent abuse now. Second, an abuser typically will go through whats called a honeymoon phase after they've been confronted or for other reasons are facing guilt for what they've done or having been caught or called on what they are doing. This is not change, neither is it usually anything but a temporary fix to get in good with the victim again. They will 'be good' for awhile, and draw the other person back to them. When they feel relaxed enough that they've got you again, the cycle will start once again. Time and again this will happen until they get help and really do face their behavior issues, you get out or something worse happens as it comes to a head.

please, do not think that he's changed after such little time nor do not expect it to be permanent. Likely it is not.

He's already escalated from being what you called "emotionally abusive" to full on physical violence. When the cycle comes back around it could likely be more violent and dangerous. The more times you allow them to draw you back in and convince you that things will be great from now oon... the more they feel they've got you and will feel more free to continue and worse, do more harm when their anger comes back.

Please seek abuse help now. don't wait, no thinking just do it. Even if this could turn out well for the two of you it will not be without you doing this and calling him on the path he's on toward being a serious abuser.

I hope you take my words to heart and seriously seek help.
