I've identified as aroace for about 4ish years now, and as of last month, I got my first romantic partner! I'm not 100% sure what my feelings are towards him (dw, I've told him about this). The only thing I can say for certain is that I want to be able to call him mine.
I hesitate to call it "actual" love in a traditional sense because it started out as an overwhelming, all-consuming feeling, but now it's leveled out. It's still there, however now it's much, much weaker than before.
Anyway, sorry, I'm rambling. The question I wanted to ask was, how do I know the difference between being an aromantic person who feels little romantic attraction, or just being allo?
Well, first off, I recommend looking into different types of attraction (tertiary, sensual, queerplatonic, alterous, etc.) to see if anything other than "romantic" clicks with you. https://lgbtqia.wiki/wiki/Attraction Or, you can just go unlabeled or make up your own label for what you feel (all experiences are subjective!).
And feelings can be confusing, especially since this is your first romantic partner. I remember feeling the same way when I got into my first QPR, and also when I romantically dated my BFF. And I had almost the same experience as you!
Actually, for me, while I do heavily identify with the aromantic spectrum (I am in fact demi-, grey-, and many other things), I prefer to be referred to as more allo (since that term fits my experience better. Yes, I do have a difficult/different time in relationships and romantic love, and I do fall under the aro spectrum; however, I prefer to align myself with being alloromantic).
And what does that tell us? That what determines calling yourself aro or allo is mostly determined by you, your experiences, and community.
If your experiences don't connect to being allo, you're probably aro(spec).
If your experiences don't connect to being aro(spec), you're probably allo.
If your experiences both connect to being aro(spec) AND being allo, you probably have fluctuating, conditional, or vague levels of attraction (aroflux, arospike, arojump, demi-, apres-, grey-, etc.).
If your experiences don't connect to either being aro(spec) OR being allo, you probably fall outside the split attraction model (differentiating between sexual and romantic attraction, or other types of attraction) or an attraction model wholly.
(For other questioning folks to know, these apply to asexuality as well. But this post will be focused on romantic attraction.)
The best thing I can recommend is taking some time to let things figure themselves out. You don't have to rush with a label for yourself. Maybe feelings will even out, or you will have that one eureka moment.
If you want my opinion regarding this (note I am just some guy running a blog): I don't know enough about your situation or how you feel, but so far, it seems to me that your experiences align with someone who is arospec or an aro with alterous or non-conventional romantic attraction. 4 years of calling yourself aroace and only now getting a relationship (along with having uncertain feelings) tells me that you're not allo (or at the very least, not a conventional one).
And as I said, these experiences aligned closely with mine, so I hope I at least had some insight on the matter! And I hope you guys have a very healthy and happy relationship!! :D
