To all the people realizing they are aromantic, even if they are in a relationship currently:
You are not using anyone nor have you inherently used someone just because you are aromantic. It is still possible to have a relationship even if you are aromantic, but if you realize you need to break it off, that’s okay too.
Realizing parts of who you are is not a bad thing, and while it may change how you approach things going forward, it does not have to, nor is it bad if it does. Figuring yourself out is a good thing. Love yourself. It’s okay.
