I feel too much pain..

I feel too much pain that ive never felt before! Yesterday i broke up with the only guy i ever loved or will ever love.. But gosh i had to, there was no other possible way to solve it and i hated to hurt him with me..

It hurts me too much specially that i hurt him.. All i can do is to move on but how!!!? I do love him a lot and i know he loves me so i have no obvious reason to hate him or to even move on!! Plus im having my finals and cant even study!! Im just reading over and over our conversation and crying all day and night!! I feel too much pain and i need help please..
