You could always ask him out. Better then living with what ifs. BUT if thats too much for you then you just need to go about your life. He's not going away but he doesn't need to be the focus of your thoughts. If you focus on other areas then he will slowly start to slip from the forefront of your mind, and this way you aren't closing yourself off to the possibility of someone else catching your eye.
