Marathon Ghosting (noun)
The act of repeatedly disappearing from someone’s life for long stretches of time, only to reappear sporadically when lonely, bored, or in need—often dragging out the relationship dynamic for months or years without genuine commitment. Unlike one-time ghosting, marathon ghosting is a cycle of using and abandoning, leaving the other person emotionally strung along.
