Aww well happy bday! If it makes you feel better people tend to be flakey on birthdays once you get out of the "everyone I know is going/the whole class is going" phase. Sucks but helps you narrow down who cares.
Also, the fact that people tend to pay for you when you are younger and a guest at birthday parties tends to fade away, leads the people just in it for the free stuff away lol
