Never agree to meet another member if you don’t feel ready. If they ask and you really don’t want to meet up yet, tell them. Explain that you’d just like a little longer communicating online, but you are interested in meeting up one day. If they are genuinely interested in you, then they’ll wait. If they suddenly stop returning your messages then they’re not worth meeting up with and it’s better to find out now what they’re like rather than further down the line.
