Will my ex come back?
The cards will not give you a date. What they will do is separate two things you are probably holding as one: whether there is still something alive between you, and whether it is heading back toward you.
Those two can disagree. A reading that says the feeling is real and the direction is away from you is not a contradiction — it is the most common answer this question gets.
We'll read this as: What's still alive between me and my ex, and where is it heading?
Cards that often come up

Something is turning, but not on your schedule.

A crossing already underway — away, not back.
The Hermit
They are somewhere alone with it, and not reachable yet.
