Ghosting

The act of suddenly cutting ties with someone you date. The term carries a very negative connotation. On Psychology portals, ghosting will be labeled as a form of psychological abuse. Thus, some people may not see fairness in using the term to refer to people who have vanished after a date or two, or after a little time chatting over Facebook or Tinder. They'd rather limit it to people who used it as a coward manner of breaking-up a months long relationship or friendship, specially if a bond was explicitly set to exist, and expectations could be deemed as legitimate and rational. While it can be that the ghoster simply doesn't care enough about the ghostee to end things right, it can also happen as a product of unhealthy relationship dynamics, such as it being almost impossible for a non-assertive anxious-avoidant type to properly break-up with a lovebombing anxious-attached one.
