@Danibox123,
Why the hell can't you tell her?
Of course you can tell her.
But don't lead with
omg I love you let's run away together.
Ask her out for a soda or a coffee. Have a lovely time. Tell her you'd like the next meeting to be a real date.
And then see what happens.
This life belongs to people who push past their anxieties and ask for what they want.
