Awwww BexxY! He is such a jerk!! He doesn't deserve you!! I went through something similar to you, except I'm only 15 (sorry, I don't mean to be on here Oldlings ) but he dumped me over email, which is probably the wors thing someone can do! , and it kind of came out of the blue... you know, I have wasted too many tears on it, and I have given up on him alltogether!
BexxY, you need to think about everything but him right now, go out and buy something for yourself that you've wanted for awhile, pamper yourself, and spend your time with your girlfriends.
We're all here for you hun!!!!
