You can't force him to want you....just let it go...and try not to think about him....try new stuff that you always wanted to do....now it's the time....
Also, you don't know about future....experience has proven me that guys always come back to your life....My ex-bfs always tried to get me back but it was always tooooo late....I was moving on already!
I heard this pattern from so many of my girlfriends....It looks like guys want the girl when she doesn't want him anymore.....now you are sad....but once you get over him, then he wants you back....now, he sees you as a girl who is there and wanting him....so stay strong and help yourself and love yourself....
he doesn't want you, then you should respect his will and let him go!
take care
