Qpr and general advice

This is my first ever post forgive me if this has been asked TT

Hiii I just wanted to ask abt "expectations" and rules in qprs (I know there's no expectations but it's the way my brain works TT)

Personally I've been in one before but it was with someone who was allo on both spectrums (turns out it was a situationship,, whatever that is) and I guess it left me with some questions.

For one, I know I want to be with someone long term w/o any sort of romantic or sexual attraction but I am very romance and sex positive/favorable (I think those are the terms ?) I enjoy doing things inherently romantic and sexual but the idea of being with someone in that sense puts me off,, ok so basically I'm bellusromantic

I guess my question would be - what are the rules and expectations of qprs ? I understand what it is but I'm still a bit confused with some things. Is there a specific thing you do or don't ? Any general things to expect ? Is it completely up to the pair ?

I'm very new to this as I've barely even realized I was aroace ! So I'd like any advice to help me out ! It's a bit vague of a question but hopefully you get what I'm trying to ask :)
