Do I text again or move on?

Hey,

So I started chatting with this girl on Tinder – and we seemed to get on well, lots in common etc.

We soon moved over to WhatsApp, and were sending massive messages to each other – text back and forth once a dayish for just over a week.

Anyway last week I asked if she wanted to meet up for a socially distant date – she said she’d love to, but was busy with work that week/weekend and following week – but suggested this weekend.

I said great and asked if she wanted to go for a walk…that was over a week ago and no reply? Not even read the message. We’ve gone past the date she suggested.

Do I send another message or just leave it, if she messages back she does otherwise move on?

Just seemed strange to go from being enthusiastic and suggesting a date to ghosting.
