I'm left wondering how we're to differentiate between girlfriend or boyfriend without actually hovering over the text to find out. I assume this is entirely dependent upon the gender of the person you're speaking with or writing to, but that doesn't account for homosexual couples. Is there something here I'm missing?
You wouldn't know their gender until a pronoun is used or it's stated what gender the kæreste is. Jeg elsker min kæreste would be both "I love my girlfriend" and "I love my boyfriend" whether the kæreste is the opposite gender to the speaker or not. Both should be accepted, if not then report it
