It's normal to feel angry. I hope you move on and stay away from this guy. I hope that if he attempts to contact you (which he probably will) that you will go NO CONTACT and don't take his calls.
Advice on how to get over a break up:
First, you need to realize there is nothing wrong with you, this relationship just wasn't a good fit. No matter how wonderful you thought it was, it wasn't right.
Next, you find the things that was wrong with your partner. Look for things that drove you crazy. These can be big things like the way he/she drove in traffic to little things like the way he/she put the toilet paper on the holder wrong. Try to identify these things as character traits so you can avoid them in the future Mr(s). Right. usually a person in your situation will go out and find someone very similar to the one that simply did not work. Try to avoid repeating mistakes.
Finally, you call all your friends and renew the friendships. Don't spend time telling about the break up etc. because you want to have fun and so do they. Don't talk about downer stuff. Having someone feel sorry for you is not nearly as good as having fun.
As you are meeting old friends, you will meet new friends and your network will grow until you find the next Right One. In the meantime, enjoy yourself and find things you like to do (not things you learned to like because of someone else)
