Card #3 represents their view of themselves.
You've drawn the Nine of Swords which has a theme of Nightmares and shows up in concepts like grief, despair, distress, desolation, illness, brooding. We rarely see ourselves the same way others do -- especially when we're in conflict -- and that's part of what's going on here. Take a moment to think about how your partner's view of themself is influencing the resolution or the continuation of the conflict.
