A straight gut-check
The difference between ghosting and busy is the PATTERN, not the pause. Busy people surface — a ten-second "sorry, slammed this week, I'll call you" is something anyone who wants you finds time for. A total blackout for days, from someone who used to be present, is a decision, not a schedule.
If you genuinely can't tell, one direct, no-pressure message gives you the answer: "hey, all good? no worries either way." How they respond — or don't — tells you everything you need to know.
