How do I confess to my guy friend who I already rejected?

At this point this guy has become one of the closet people to me. I didn’t know him as well when I originally rejected him and honestly I was at the time afraid of using him to get over someone else (which i’m pretty sure i would have done if i originally went with it.)

Now i’m completely over the other guy and I feel more ready to be in a relationship because i don’t think i was at all before. We talk everyday and go everywhere together. It screws with my mind when i remember we’re not together considering we act like it. Should i confess to him or leave it alone since i already rejected him before?
