What is jump then fall about Taylor swift?

The song "Jump Then Fall" by Taylor Swift is about taking a risk and being honest with someone about your feelings. It's a story of unrequited love where Swift is attracted to someone who is either a friend, already taken, or otherwise unavailable. She knows she should tell him how she feels, but is afraid of the consequences and worries that her feelings might not be reciprocated. Swift's lyrics talk of how she longs for a relationship with this person, wondering what it would be like if they just jumped into a relationship. She feels like she has to take a risk and be brave, to face the possibility of falling or getting hurt in order to find out if her feelings are real or not.
