I agree that he doesn't care. That isn't to say he might not put on a show of remorse at some point, just to reel you back in. That's a pretty common scenario. But he doesn't DEEP DOWN care--not enough to change. And if he really cared how you felt he wouldn't have treated you that way to begin with. He felt a certain ownership of you, and he might not take kindly to your breaking up with him, so it pays to call an advocate to make a safety plan.
As much as it hurts, you can recover from this. An advocate can also hook you up with resources like counseling to help with your healing. But it is NOT SAFE to stay in this relationship--whatever he says or does to try to convince you.
