This is kind of a vent, looking for advice

For the longest time, I used to think I was aroace, but recently, I've realized I do feel sexual attraction (ace spec), and I think I may be cupioromantic.

My question is, how do I deal with this?

Up there is the question

Down here is the vent

TW: a bit of internalized aphobia

For so long, I was upset about being aroace because I felt a bit "broken" but I overcame that and accepted it, and I was finally happy! But being just aro makes me feel like shit... I tried relationships, but I just feel nothing twords the other person, and maybe they weren't right, or maybe it's just not for me, but I REALLY want it, and I don't want to feel like I'm using the other person, it's also not what I'm doing but it feels unfair to them. I don't even want to have sex with anyone. Honestly, I wouldn't mind being aro if I was also ace, but being like this just feels like my body and my heart want the same thing, but my brain isn't prudenceing the chemicals.

Sorry, I just really feel helpless...
