Suffering from a brake up.. Need advice ?

I've broke up with my bf today. Lately I've been giving him my all and I never known myself to fight so hard for s relationship. O put all my love body mind and soul into this and lately I've been telling him that I been needing him because I felt that he was being too distant . Told him several times last week the week before last and he still haven't showed me he cared. I came home yesterday from a long weekend.. Did u know that he didn't greet me.. We smoked a blunt then he left like I was just one of his buddies .. It hurts so bad and I feel it's somebody else and I feel he doesn't care.. He doesn't answer my phone calls he don't show me he loves me... And I'm so depressed because of it...(tears) I'm so hurt because I don't deserve how he has been treating me.. Uhhh it just hurts so bad!!! I need some friendly advice on what to do.. I appreciate everyones answers and concerns I really do!! Thanks!!! Xxxoxoxo
