I have been messaging this girl on Bumble (misleading title, I know) for about a week - Obviously she messaged first so she's kinda keen. It always takes her about 1-2 days to reply, but the conversation was good and she was responding positively, lots of "hahaha"s, etc. So I asked for her number, but she hasn't replied after 3 days.

Should I send another message? Or just wait.

And furthermore, what's the best way to keep them engaged on dating apps? A lot of the time the conversation just dies... but I'm not good at text game.
