i need help

so i’m kind of in love with this guy. and i know i’m “too young” but i feel like this guy is perfect for me. he has recently moved across the country and i was devastated. he’s coming back to visit and i think he might like me but i’m not sure. he said he wants to meet up and i’m scared. i mean i still love him. we’ve dated before which is scary. anyone have any advise or wisdom. i’m kinda clueless 😕
