First of all, it will help you if you can get over the idea that you’re friends. You’re not. Friends don’t fall in love with each and want to date each other. That’s different. It’s romance. So if you can understand the difference between friends and romance, you’ll have an easier time understanding that you’re not friends and you can’t be. That will simplify a lot for you!
Second, decide if you want to date him or not. If you do, then flirt with him and let him know you made a mistake in cutting off with him because you didn’t want to be in the middle. But don’t go back to the friend zone. With your actions, make it clear you’re interested in dating.
And third, if rejection comes, accept it and move on. Life will be less chaotic and stressful for you, and you’ll be open to dating someone else because you won’t be in a complex friend zone with a guy you like as more than a friend. 😉
I hope that helps!
