Are there some good words in English for "a committed long-term relationship that isn't marriage"?
Picture two people, who may not even live in the same physical space, who are in a committed relationship but who have no desire or intent to get "married", or desire to use the terms husband/wife/spouse.
What is a good marketing term for that sort of thing?
Partner? Significant other? Boyfriend/girlfriend/...? Comrade? Fellow-traveler? Love-o-my-life? Shieldmate?
