What’s the best way of getting over a person?

I’m planning on being celibate for the next 5 years of my life. At this moment I’m recovering from a heart break. So I just wanted to know, what is the best way of moving on and getting over a guy who played you? I didn’t block him, because he isn’t gonna message me or try to apologize to me. So I’ve just sort of fallen back and now I’m silent and in my own world.
