How long has it been since she responded. If you just met her this weekend, she might have things going on. You shouldn't be wasting your time TXTng small talk back and forth with someone you just met. Use small talk as something to fill the dead silence between more important engaging conversation when in person.
You should have proposed a meetup sooner. Like within the first few txts. Maybe this will work. But it could fuÁk it for you too. you need to deflect her interpretation of your interest in her:
"... as a friend. It would never work out between us. You're like my little sister. Kinda of a brat. :-)"
Or some "neg-like" playful comment that is more congruent with your and her conversation.
