I agree very much with the need to distinguish between Romantic as the relationship type and romantic in all other senses. However, I'd like to talk about my own relationship as an example of why I'm not so sure that distinguishing between these solves everything.

I'm an aroace in a Romantic relationship with a person who has romantic feelings for me. However, although our relationship is labelled Romantic (it's important to my partner) it doesn't really fit into the Romantic mould at all—we have very specific rules about who is allowed to kiss who and where and how, I often respond with "gross" to romantic statements directed at me because I'm very romance-indifferent, and a lot of tropes and ideas about coupledom really really disturb me.

Basically, it doesn't look like what people think of a Romantic relationship at all. I think it looks a lot closer to a queerplatonic relationship but then it becomes "my Romantic[category] relationship can be queerplatonic[attractions/feelings/actions]" which... I'm not sure is the right way to go either.

I think if there must be a clear and mutually exclusive divide between Romantic and queerplatonic relationships, the definition of Romantic needs to be made looser or something because right now if I say to people I have a Romantic[category] relationship, it's assumed to also be romantic[attractions/feelings/actions], which is only true of my partner and not true at all of me.

The statement "Queerplatonic relationships can be romantic" I think I would agree doesn't really make sense, but only if you consider "romantic" to mean "romantic all ways from all involved parties".
