The best break up revenge ever

I was nervous about going to my friend’s birthday party because I knew my ex-girlfriend would be there. It spent all week talking myself into going. At first, I was just going to support my friend. But later I figured it would be the best way to prove that it wasn’t hard for me to get over a break up. When I got to the party, no one even mentioned the break up. Sure my ex-girlfriend showed up but ti didn’t bother me. She brought some other guy but he was busy flirting with the other girls. So much for her trying to make me jealous!
