The gap between the budget you wrote and the life you're living.

means The amount by which something — usually money — falls short of what's needed or expected.

from A straightforward compound from 'short' (lacking, insufficient) and 'fall' (to land at a certain point), emerging in financial and economic English to describe when a sum fails to reach its mark — the way a thrown object falls short of its target. No hidden story here: it's exactly as literal as it sounds, which is perhaps the cruelest part.
