What if I went to a "heart-broken-feeling" whether I doesn't have a boyfriend..and i want to moved-on?

bec. i realized that even if i will say my feelings to him.. nothing will happen bec. i know that he doesn't like me or he will not love me in return, even if we're bestfirends/friends.but now were relationship as friends is "blur" i mean that, its impocible to be us! and only few times that we greet each other or say hello. so, my feelings wants to stop loving him,even if i love him,i said to myself "i will stop this idiot-love!!!"please help me to moved on! what will im gonna do!?
