Ex wants me to go to a party ... need advice?

i don't think it was a bad idea, thats good if you guys are friends&you should go to the party have fun if you see him flirting with other girls and it really bothers you leave or you go ahead and flirt too! you could also maybe take a friend he doesn't have to like he can just be your friend and have fun with him. if he really still liked you and missed you he probably won't be flirting.
