It’s fine. There isn’t a really unambiguous way to ask someone out via text that both makes your intent known and isn’t weird or creepy. “Do you want to go on a date?” is not how people talk. If she accepts, you have the opportunity to charm her and achieve your goal. But wanting it to be known going in - “I want her to know she is on a date” - is only meant to make it easier on you, to have that clarified on the front end. Don’t be like that. Get better at in-person relationship-building.
