After breaking up, my boyfriend sent a text message to say hello. How should I reply? Be anxious to wait online.

Just be an ordinary friend and observe what he really wants to do. If you want to make up, if you don't like it, you can refuse. If you like, you can say that you will reconsider and delay him for a while. Actually, face is not that important, depending on what you think. Don't miss a good relationship to save face.
