Nothing wrong with your text... she just has low interest. I doubt any better response would have mattered. I never text a woman I'm interested in. I would have called her and asked her to have coffee... drinks so she could tell me about it. Always assume when a girl reaches. out to you it means she wants you to be a man and try to make a date. That way if she shoots you down you have a CLEAR signal to move on. As it stands now you are acting like a chick trying to figure out what her lack of response means. You can still recover call her try to make a date... whatever happens you'll know where you stand.
