Why did they pull away?
Distance almost never means one thing. The useful question is whether they moved away from you, or moved away from everything, and the cards are unusually good at telling those apart.
A five-card reading looks at what is helping, what is in the way, and what you can actually do — which matters here, because most of the answer is not yours to control.
We'll read this as: What changed on their side, and what is it asking of me?
Cards that often come up
The Hermit
Withdrawal that is about them, not about you.
Four of Swords
Rest, not rejection. They stopped, not left.
Seven of Swords
Something is being handled quietly instead of said.
