I understand the story now. I asked spirit who he wants to make his offer of love to, and I clearly see that he is torn: https://i.imgur.com/XagvUsa.jpg
Him = Hierophant and 2 of Pentacles, juggling his choice
Me = Queen of Cups clarified by the Star
Her = Queen of Wands clarified by the Queen of Cups
Knight of Cups = his offer to me
6 of Cups = his offer to her
Sun = this card popped out of the deck when I was asking about his offer to me
I think he's been with her for longer, and has a sweet nostalgic attachment to her (6 of cups), and is therefore feeling as though he owes an offer to her. But the Queen of Swords clarifying the Queen of Wands makes me think she might be a karmic partner.
With me clarified by the Star, I think he sees me as a form of wish fulfillment and that I bring him incredible happiness. The fact that I was clarified by a major arcana (and a positive one at that) makes me feel like I'm the soulmate and she's the karmic - but this could just be my own bias talking.
