A relationship that exists mostly in your head, built around someone you have little real connection with.
An imaginationship is a romance that lives largely in your imagination. You build a detailed story about a future with someone, even though the real bond between you is thin or barely exists at all.
It often grows around a crush, a celebrity, a coworker, or someone you barely talk to. Your mind quietly fills in the personality, the chemistry, and the entire relationship that has not actually happened in real life.
The danger is mistaking the fantasy for evidence. You can feel deeply attached to a version of a person you invented, then feel real grief when the actual person never plays the part you wrote for them.
This sits near the habit of idealizing partners during the early love haze. Reality-test it by noticing how much you genuinely know about them versus how much you have imagined. If the connection only feels strong in your head, you are dating a daydream, not a person.
