Fleetuation

Experiencing intense romantic and/or sexual feelings for someone that only lasts for a short amount of time. Fleetuation often ends when the person experiencing it realizes it would never work out or that their feelings are only one way. After fleetuation the person is able to move on with their life like they never had a crush in the first place

"she's been experiencing fleetuation ever since that new guy showed up, I don't think she knows he has a girlfriend already"
