What do you call the significant other when you're not married? →[More:]We live together but I hate the word "sambo" (swedish word for living together "samman(together) + bo(live)"), we have a child together but father-of-my-daughter is too dang long. We're Boyfriend/Girlfriend but that sounds so highschool. I've resorted to calling him "My man" sometimes but that's just off. Lifepartner sounds too new age. Please, isn't there a word for man-you'll-always-be-with-but-will-never-marry? Should I go get a ring just to upgrade him to "fiancé" which is a nice word?
