People can only make you feel worthless if you let them.
So stop your "stinkin thinkin" and don't let his behavior have any power over your feelings. Don't let him win.
And wish the other girls luck - they are gonna need it, whereas you have a whole new life to live!
You will find someone who is worthy of what you have to offer. And you will someday look back on this and breathe a huge sigh of relief.
Hang in there!
