A flirtationship is an ongoing flirty bond with someone that never becomes an actual relationship.
A flirtationship is a connection built on persistent flirting that stays in a gray zone, more charged than friendship but never developing into dating.
It shows up as steady banter, teasing texts, and obvious chemistry with a friend or acquaintance, yet no one makes a move to define it or act on it.
It is close to a situationship, though a flirtationship usually stops short of romance or physical involvement.
These can be fun, but they can also stall you with someone unavailable. Decide whether you want more, and if you do, say so, because a flirtationship only changes when one person risks naming it.
