Ask How do you deal with a client who keeps sending messages but never actually confirms the project?

[Edward22]

Sometimes a client keeps chatting, asking questions, and even discussing ideas, but never clearly says they want to start the project. This can waste time because you stay available without any real work or payment agreed. It becomes hard to know if they are serious or just exploring options. At what point do you step back or ask for a clear decision? How do you handle this situation without sounding rude or losing a possible opportunity?
