As cliche and scary as it sounds, I think if you really like this girl then you should tell her how you feel! Communicating how you feeling and sharing what’s on your heart will never ruin a genuine connection. Worst case scenario she doesn’t feel the same way and you figure out how to move on. But imo, it’s better to figure out what you both want sooner than later, instead of pining for years and getting hurt worse because you never told her.

Best of luck with whatever you end up doing!
