I've been talking to someone online for a couple of days and he has suggested we meet up for coffee. He says he isn't on the app much (although he has previously replied very quickly to my messages) and gave me his number to organise coffee. AIBU to prefer to keep it on the app until after we've met up and then if we both want to see each other again, swap numbers at that point? Will he be put off if I tell him that?
