"Love" (L'Amore") was the earliest known version of this trump, and it depicted a marriage with cupid there to bless it. Later, it was changed to The Lover (L’Amoureux) which, got mistranslated into English as "the Lovers." Most of the images for the "Lover" card featured cupid shooting his arrow at a man who was gazing at a woman. Thus, the implication that THIS love was decreed by some higher power: either the gods or a psychic energy by which the man recognized his one-true-love. The Rider-Waite card goes for an Angel in this position, with Adam and Eve. Eve is literally made from Adam by god, and so to be whole he has to be with her. Thus, Heaven itself has made them for each other.
I don't always go by pictures or symbols on a card either (since many illustrators have their own perception and meaning of the cards). Plus may times a card that is often seen as "negative" to many people turns out to be very positive in meaning for me (even if the symbols are very negative). I could have sworn the card was always called "The Lovers" and when you translate the meaning from plain English to Spanish it translates to "Los Amantes" (which is what we call a person who is married yet has an affair). I use Tarot to make predictions of the future mainly and in all of my experience with both personal and clients..Lovers doesn't mean a loving union at all, but a choice, or a third party..or just simply someone dating more than one individual.
For example I'd always get "Lovers/Empress" as a common combination as to how I man I was 'obsessed' with felt towards me (I was in a relationship with the father of my children by the way). We never really got together or in a relationship..we would argue most of the time and he wasn't entirely single even though he wasn't in an official relationship he was still in love with his ex, and had some sort of friend with benefits around still. I definitely don't have many positive things to say about the Lovers card when it comes to love.
