what quality my ex likes the most about

Your ex most valued the way you could meet them in friction and still bring it home — push back, hold your ground, keep the spark alive without burning the house down. Five of Wands reversed points to that quality of meeting challenge together rather than winning it; the friction didn't tear the connection, it gave it a pulse.

That is a read of what the dynamic between you most likely carried. Cards don't report another person's mind — what they liked then, or feel now, only direct contact with them could show.

Check inside 48 hours, on your own: write down two disagreements you and they had — what you did, what you refused to fold on, how you came back to the room afterward. The shape of how you showed up in those is the quality the card is pointing to.
