Trusting your intuition is one thing but just wanting to see a fated union or soulmate union or love in that card isn't the total answer. There are three people in the card in most decks unless the deck creator wanted to cut out the 3rd person so the card would always mean a love union. The third person could even signify that there's to be an arranged marriage depending on the culture. Or it could mean a love triangle if the 3 of Swords and one or two others show up.
Also, the way I read, I usually have to see other cards in the spread that would point to a love relationship, like 2 of Cups, Hierophant, Ace of Cups, 10 of Cups and sometimes some others. However, odd though it may be, I think 2 of Cups is a much better indicator of a love relationship or a potential of a friendship growing into love. Even with the 2 of Cups, if it's in a bigger spread, there still have to be other cards indicating that's what it means, though.
