Cute musician chick. Massive investment at start, followed by bratty vibes. How to deal with this?

Met this girl at the bar. Set went decently well, but I had to bail to some afterparty. Got phone number. I don't have screenshots, since this is on foreign language so I'll write it down. This is the interaction. -Sincord H: Hi there ;) -What trouble you've been causing since we met H: Just finished the walk, going to cook a lunch. Have some music lessons later, and then I need to study for college, exams are coming next week. -Just finished workout, looking fit for that event tonight. Any concert soon H: Nice, what event? I'm actually thinking about quiting band. Not sure if I can make it all timewise. And I've got a bit burned out by it. -Classic, we stopped making music for similar reasons 2 years ago. H: You were musician? -Ye, I was. Didn't we talked about this already... H: I'm not entirely sure haahahahahaha. -Guess we will have to repeat it soon. H: hahahhaah maybe -Let's turn that maybe into yes H: Let's not ahahahahaahah -You're right. You wouldn't be able to handle me H: Look, it's not question whether I can or can't, but whether If I want to or not How to salvage this? And proceed to close this girl? Need some serious help. I can't think of a comeback to this.
