First everybody was up in arms about "ghosting," the dating trend where people mysteriously stop communicating, never to be heard from again. While ghosting is totally disrespectful, it makes it easy to get over someone because they've probably made you angry.
Now, people are furious about a new, passive-aggressive trend in online dating: "breadcrumbing." That's when you're interested in someone and they communicate just enough to keep you hanging on.
"[Breadcrumbers] communicate via sporadic noncommittal, but repeated messages — or breadcrumbs — that are just enough to keep you wondering but not enough to seal the deal (whatever that deal may be)," Jessica Bennet of The New York Times says. "Breadcrumbers check in consistently with a romantic prospect, but never set up a date."
