How do I get over this?

I recently ended things with my ex boyfriend because we weren't working out. Things were great in the beginning and I had never had anyone treated and cared for me that way but towards the end he changed. I was unhappy and I told him multiple times. I then decided to end things. When I was breaking up with him, he got angry and began to throw things back into my face. He even told me that he should have emasculated me and used me for sex just like the men in my past who I've slept with but who didn't treat me half as good as he did.

I had no problem walking away for my own happiness but when he told me that, my heart broke and I've been crying on and off ever since. Some days are good because I don't have to deal with him and others are tough. How do I get over this?
