You are definitely doing the right thing.
He's taking your love for granted, and he will keep doing what he's doing until he's stopped. If he gets locked up (and he probably will), please don't bond him out. He needs to feel the full consequences of his actions.
He will probably alternate between promising you the world (if you'll drop charges) and blaming you for everything.
It's all on him, and I hope you can put your focus back on you.
I think the restraining order is a good idea. I know this has to be very painful for you, but I promise you, that letting him fall flat on his face and figure how to get back up is the best thing you can do for an addict...at least, it was for me.
Hugs and prayers!
