Time will help, but you might want to seek out a therapist for yourself. There is nothing wrong with seeking help out for yourself, if you haven't done so already.
In my own case, forgiveness was key. Not in the "it's all okay I will take you back" way, because forgiveness doesn't mean that. I won't forget what he did, I found out many more nasty things when we split, but for me the conscious act helped me to release the anger that quite honestly he deserved. It just sort of happened, when I thought I could be consumed by anger, or I could continue to build upon the rich life I had established for myself prior to meeting him, and had continued with during our relationship.
You see, the one thing you will read over and over again from supporters and sufferers alike, is that you have to continue to have a life for yourself, take care if yourself, do things for you. If all goes well, you will have interests to talk about. If not, you are not lost. Angry, sad for awhile, but you learn, you mend, and you continue with what you have built for yourself.
Get out with friends, travel by yourself, do things that make you a better person and enrich your life. The anger is normal, the sadness is normal, and you will grieve it in its own time. But it will dissipate. In the meantime do not be afraid to seek out professional help. Remember you have to be worth it to yourself, before you can be worth it to anyone else.
Hang in there.
