Ghosting stings because it leaves you without an answer. The first thing to know: it says more about their avoidance than your worth, and no message can force a reply out of someone.
You get one dignified final text if you want closure or a clean re-open. Anything angry or desperate closes the door for good.
A single relaxed message after a week or two is the ceiling. A string of texts confirms the awkwardness they were avoiding.
No accusations, no essays, no asking what you did wrong. Calm and light is the only tone that ever restarts a ghosted thread.
If the final text gets silence, that is your answer. Take it and move your energy somewhere it is wanted.
One calm, low-pressure message is fine if you want clarity. Skip it if you only want to vent. Either way, send it once and accept whatever happens.
Usually to avoid an uncomfortable conversation. It is about their discomfort with conflict, not your value.
You can reply if you are still interested, but it is fair to mention the disappearing act once, casually, and watch whether their effort actually changes.
