I do find it unusual that you are so focused on who is making "the moves"
Is there anything that has been keeping you from actually...asking R out for a date? Or tell R you want to be asked out on a date?
Might be totally off based but from here, one thing I thought was "Qarzan kinda likes R but has gotten distracted by H who is shinier (assertive), so has used that as a reason to not bother to get things moving with R. Maybe Q doesn't like R as much as they think they do."
Anyway, sounds like maybe both of you are procrastinating if you and R know that you have intent to date, I'd get to that poly conversation and ask them out.
Happiness will never come to those who fail to appreciate what they already have.
