i don't know what to do

i really like this boy, but i don't think my heart wants me to so i can't feel as much for him as i want to. like i really really like him, but ive been hurt so bad in the past. he doesn't seem like he'd do something to me but im so afraid of disappointing him. im so afraid ill fall and he'll leave. i don't think my heart is ready for that. i don't know what to do

im sorry if this sounds dramatic im just so confused
