How to break friendship without hurting him?

Ok.
I love him very much. proposed him for 2 times but he refused. still we dint break our friendship. But now I can't handle this anymore. I can't talk to him, cuz whenever I talk to, I fall in love with him again n again. I want to break our friendship, but without hurting him. I dont wanna complicate my life, as my family is searching a boy(for my marriage).
Plz help???

U can tell him that u love him so much.. And that being only friends is hurting you.. And tgat your parents are searching for a guy to marry you.. N u dont want any one else.. Then say that u are sorry .. But ur love for him is too strong n u cant continue this friendship (:
