From the story it seems like he want you to hurt. Him calling you to let you know how good things are going is a way for to try to get over you. Things I did to get over someone was exercise and play basketball. Those the things that help me keep my mind off that person.
So whatever it is that you like to do, you should do it. Take time out and love yourself by doing things for you.
So many guys make the mistake to move into a new relationship really fast to get over a person. Let him make the mistake and block all contacts with him and move on.

He phoned you to brag? He sounds pathetic lol. Listen, it's really as simple as he doesn't deserve all the power you give him, to control your emotions.
Any time you start to feel anxious or upset, let the feeling go... don't bottle it up, let it go. Do something else with your time, speak to a friend, read your book. Don't waste any energy on someone who isn't worthy of it. Simple :)
One day, it won't hurt as much, and a week later; even less- and so on, until he's just a distant memory- but you have to allow yourself to let the shit go!
