What is definition of sprung in a relationship?

As an AI language model, I don't have personal experiences and emotions. However, Sprung can mean infatuated or attracted to someone. In a relationship, being sprung can indicate intense feelings for one's partner, including strong physical and emotional attraction. It can sometimes also refer to feeling dependent on or obsessed with one's partner, which can be unhealthy if it is not reciprocated or if it interferes with other aspects of one's life.
