Conversation went from perfectly great to "actually I'm busy". Can anyone point out something I did wrong? Frustrating when I seem to get a good conversation going and they flake out. https://imgur.com/a/AHRGakt

As a background I matched this girl on Bumble last week and I asked her about meeting up last weekend but she was busy at her parents, I asked for her number and then I texted her once on the weekend (she was out with her friends at the time) and then again Wednesday to set up the date. Did I wait too long to set things up? Seems like she was still interested until she responded the next day "I'm actually busy". I've only ever set up 2 online dates before, and one was a terrible virtual date that did not work out technically lol. I'm just get frustrated when things seem to always go nowhere, it's seriously discouraging and just makes me wanna be single forever
