Search Results: good conversation

I know this kind of topic comes up a lot, but my situation has a twist.

About two years ago I matched with a girl on Tinder. We moved over to Messenger (because we both felt we vibed) pretty quickly and had long, positive conversations with a really good flow. After 4–5 days I suggested a phone call, and we exchanged numbers, though we never actually ended up calling.

Shortly after that she said she felt unsure about what she was doing, and the conversation slowly fell apart. Eventually she told me she didn’t want to continue talking, so I respected that and we went our separate ways.

Fast-forward to last weekend: she matched me again. She responded to my opening message with a friendly, genuine reply. She also said she remembered our previous conversations and that she found them fun. She asked questions back and kept the tone light.

I replied 1–2 hours later the same day.

Since then, it’s been around 40 hours with no response, and Tinder shows she hasn’t read my message yet.

If this were a completely fresh match, I’d assume a ghost and move on.
But this is someone where we already had compatibility and great rapport before.

So I’m curious; why do you think she chose to rematch with me after two years?
Even though she hasn’t replied yet, should I still assume it’s a ghosting situation, or is it different in a case like this?

Also, should I (see polls):
