Thank you for this! I've been wishing of late that we had a word for this, which I think might help - the slash/friendship distinction, imo, dates back to the separation of slash and gen lists/fic/comms, which is thankfully less heavily enforced nowadays.

But our classification language is pretty much useless in describing "passionate friendship" or non-sexual romance, and I know that as a writer I've been frustrated by it. How on earth do you tag a "so married but not doing it" story? Where do you post it?

For people who still buy into the idea of a slash/gen boundary - versus, like, relationship-centric and casefile stories - romantic friendship is something that requires careful policing, because it really threatens that binary.
