Am I aro?

This is my first time doing this and im a little nervous but ive been feeling as im aromantic or at least on the aroace spectrum as well but ive had multiple relationships in the past and im trying to get into one with someone but im not ready and neither is he. He knows i identify as aroace but im not sure if i want to try being in a relationship anymore. He's great and all but i feel as if my feelings are always fluctuating from little to all or im having trouble trying to figure out if a relationship is what i REALLY want.

there is this other guy that i met, lets call him J. J is amazing and a great guy to be around and I feel like I enjoy being with him more than i enjoy being with almost anyone else. It’s not like i want to be with J but i really like the bond that we have and im seriously not looking to be with him. He just makes my days a lot better.

I’ve been feeling lately that I don’t need a partner, I just need a friend. And there are times where I just intensely crave a relationship with someone or just someone to love me entirely and whole with no expectations from me but then my thoughts change almost immediately and it just seems overrated. Could anyone help out or give advice? Im more than down to listen.
