Move on or follow up? (online dating)

[jpbomba21]

Quite new to online dating and I'd matched up with someone who I thought had a good back and forth with.  We'd been talking for a few days with pretty detailed replies and questions.  The last exchange I replied to a question that they asked and asked my own, and was actually thinking of asking to meet depending on how the response went.

However, it's now been a few days and I've not heard anything and am not really sure what to do.  I'm aware these things happen with online dating so don't want to overthink it.  Part of me thinks to just leave it and move on, but another part thinks it might be worth sending a follow up maybe asking of they wanted to meet for coffee?  If it was just one message and nothing I would leave it, but it looked like it was genuine interest to me, but maybe I'm wrong.

Any advice is appreciated.  Thanks,
