I'm not sure if I'm aromantic. I might be demi-romantic. However, there are some girls that I do like. However, I don't like how the very idea of showing a great deal of appreciation for their existence can (at times) come off as if I'm trying to establish a relationship.
One thing to remember is that just like with every single identity there is a spectrum. Even with aromanticism too. There's a spectrum with how aromantic you are, how you show how aromantic you are, and how willing you are to push your boundaries for someone. So for you, you might be comfortable liking someone if they are right for you, but not be willing to be classically romantic with them. Just find what works for you and what makes you most comfortable and remember to be honest with yourself and those around you.
