I need help fast! please help me. this is sad! boys!!!?

so i knew this guy for a whole year, and we were together for 3 months. he told me he loves me, and we did so much together. i feel like we really loved each other, but he broke up with me recently because we cant see each other that much.. and he feels like, if we cant see each other, then theres no point to our relationship. but i am crushed. he ignores me all the time, but when he found out i told his sister about us, he actually talked to me and asked me why i told his sister.. i kept denying it though. i am so desperate. i cant live without him. he ignores all my sweet messages, like it was nothing. i want to die. i cant do it anymore. i want him back so badly, i will do anything, but he doesnt appreciate that. what do i do? i cant forget him, or move on, or get over him. it hurts so bad. i want to kill myself
