Sweetie, did you really expect a 14 year old to be mature enough for a relationship? For that matter, did you really think you could handle a relationship at the age of 12?
You can't get even, he doesn't care.
The best you can do is stay single, be a child, concentrate on school and friends, and date when you're old enough. That won't be for a few years yet.
Definitely don't follow Joy's advice and get drunk. Bad advice for anyone, especially a 12 year old. :(
