I would. But I would also bring up the “why it was dropped” topic. Its the 800 lb gorrila in the room, and ignoring it does not make it go away.
Sort of what Aries is saying, but I’m more optimistic. I cannot imagine anyone dropping someone because something better came up, and then going back to the “lesser” choice.
If anything, the drop was due to a misunderstanding or just cold feet. Neither of which is a dealbreaker. But should be addressed so you can both move forward.
