im so upset.. im 15, my first serious boyfriend. we've been together for about 5 months, but he has changed towards me, and he doesn't treat me right any more and talks to me once every fortnight. I know I need to end it, because it's giving me too much grief all of this and I have tried talking to him so many times. It's going to break my heart - I don't know what to do, I can just see now how upswet I will be even though I know it's for the best. What should I do.. ?
