Hi! To me, it does seem like you're aromantic.
Honestly, there's no such thing as being aro enough. Aromanticism is a whole spectrum, and you could lie anywhere on it. Not all aros are repulsed by romance, some of us may like watching romantic stuff, but that doesn't make us any less aro.
The fact that you haven't had any crushes and don't like the idea of a romantic relationship are strong pointers that you're aromantic.
If you feel like the term 'aromantic' doesn't exactly fit you, you could look into greyromantic, or other labels under the spectrum.
I personally found this to be quite helpful while I was questioning my identity.
