Happy Pride Month 
I just want to start with the fact that our experiences aren't the exact same (I'm non-binary AFAB) but I can only imagine how confusing it must be to question your identity. I just want to say that, whatever makes you feel comfortable in your own skin, does not mean you're "attention-seeking" or "faking" - It's your right to express yourself the way you want! If you believe you're trans then you have every right to identify as such, but if you think you're something else that's also okay. While labels can help many people in the LBGTQ+ community, sometimes it can be too confusing and it's fine to not stick to any labels either. What really matters is that you're happy and people respect/support you for who you are.-snip-
I've used the aromantic label for three-ish years at this point - so since I was fourteen. Also just to note before I get into everything, it's alright to think your aro and then it turn out that you're not, even after a long period of time. Don't fall into the mindset of feeling like you have to stick to a certain label once you've chosen it or used it long enough. It just makes you miserable.The thread doesn't explicitly state romantic orientation but I assume this is still a safe place for (questioning?) aromantic people?
I'm wondering if I'm aromantic. How does one know what romantic attraction is supposed to be like?
I'm Queerplatonic and have been in a Queerplatonic relationship before(though I suppose it was a bit too romantic for my ex's liking). The term Queerplatonic doesn't exactly have a "one size fits all" definition though the relationship you described with your QPP does seem to fit the bill of "not friends, dating or roommates but something else entirely".-snip-

Both Aromantic and Alloromantic people can be Queerplatonic as it is a specific relationship dynamic just like Polyamory. The term is most commonly heard in the Aromantic and Asexual communities but it's not exclusive to them.
It's okay to not understand if you are Aromantic or not, I've identified as Aromantic for nearly six years now though sometimes I question if I really am Aromantic or where I lie on the spectrum, if I'm Demiromantic or something. Labels can be helpful to some people if you want to use them but labels cannot always explain complicated human feelings, it's okay if you don't want to think too hard about it, explain how you feel to other people Etcetera. Your identity doesn't need to make sense to anyone(including yourself) in order for it to matter. Your feelings are valid even if they are hard to understand.
"Love" or whatever word you wish to use exists in many forms and doesn't need to look the same for everyone. All forms of love are beautiful and should be celebrated. Just because your relationship isn't inherently romantic in nature that doesn't mean it matters less compared to everyone else's relationships. Don't ever allow anyone to make you feel like you are "missing out" "broken" or "lesser than" because you don't want to date, get married or have a stereotypical romantic relationship.
You seem to very happy with your QPP, if you are satisfied with your own self and your relationship then I don't think it's an issue that you should allow to cause you negative feelings. Keep living your happiest life, who cares if nobody understands.
