Why is she ignoring my messages after agreeing to dinner?

Me and this girl have been swiping right on each on multiple different dating apps for the passed year and a half. We’ve had multiple long and good conversations, follow each other on Instagram. I’ve asked her out once before but she said she had a lot going on in life at the moment. Which turned out to be true because he son was actually going through a serious health problem. Well this last time we matched on a dating app (3 days ago) I messaged her on Instagram and said “we can continue to periodically swipe right on each other or we can finally decide to meet up. How does dinner sound” and she responds positively to that and even decided on a day. So I told her I would look into reservations that night and get back to her. And she says “sounds great”. I message her a few hours later and say “hey anywhere decent in my area is pretty much booked I really don’t mind driving 30 minutes to your area. Totally up to you I’ll find something either way” this was about 48 hours ago and we’re supposed to have dinner Saturday (2 days from now). It’s Instagram so I can see that she read it. Why would she just ignore me when she has consistently kept matching with me on dating apps time and time again? I mean if she wasn’t interested why would she just say no to me asking her out, come up with some excuse or just ignore me in the first place?
