How do you move on?

So I've been in love with a straight best friend of mine, he knows that I love him. But despite everything he doesn't wanna get back to the way we used to be just as a friend as i kinda freaked him out (quite natural) but then again i had only one good memory in the earth & that's only with him (not that I am an alien or smh) i know i can never live without him. It's been 6 years now. More the year passes I think the feeling gets stronger idk. I lost the friendship I had once with him and I know it's my fault that i came out to him. I should have give it a second thought before doing so. Idk how to move on. I tried! Give me a solid suggestion of moving on.
