Also, if she arranged to meet up with you, you'd be going there expecting it's another date, thinking things are going well. Do you really want to get your hopes up and deal with them getting put down, feeling like you've wasted an evening?
Personally, if it's not a relationship, I'd rather they just tell me over a text. Though I'm saying this as somebody who recently arrange to meet somebody for lunch to end it, chickened out and did it that evening over WhatsApp instead.
