This boy frustrates me?

this boy has txtd me and told me im pretty and sexy and cute, etc. and so i figured he was into me so we set up a double date with friends. i was busy for the next weekend so we scheduled it 2 weeks ahead (the date was set fri. the 13th). this boy doesn't talk to me for a week so i set up a 'deadline' that if i didn't hear from him 3 days before the date, i wasn't going to go. and he started talking to me hours before the deadline was up! he said he was still going so i went. he never showed up and made a bullcrap excuse that he had a fight with his dad. i tried to tell him that it wasn't cool and he never answered. i checked his facebook yesterday and there are posts on this other girl's wall saying that she was his girl and that they were perfect together. i still want some kind of closure but he won't answer me. what do i do?
