More or less, yes. Our conventional vocabulary around romantic relationships is lacking and indicative some of the failings of our culture.
I think “boyfriend” goes along with the general lack of proper rights of passage, and our society’s general failure to actually create full adults, or to relate to our adult men and women as full adults. Particularly in the USA, grown people are treated as subservient children rather than adults, in at least as many ways as not, and I think the language of boyfriend/girlfriend, and to spread shame and disrespect through metaphors of unready youth, and I think the “dating” conventions and their vocabulary are part of that. It’s full of poor terms for things, and poor ideas about relating to those we love and are intimate with.
