I know EXACTLY what ur going through, I'm only 15 and this already happened to me. We were together for a year and 3 months. I love him. The only real difference is that he did leave me for Another girl. from personal experience, i think you should separate yourself from him for a while, especially if he is hurting you. If you care about him, You can do it from a distance through his friends and family. Its working for me good luck!!
