Send a text message to the other party saying that they broke up, and there is no response. Does it mean that the other party acquiesced?

In fact, it can also be said that the other party acquiesced. On the one hand, from his point of view, he actually wants to break up with you, but he just doesn't know how to say it. But on the other hand, it can be said that when he suddenly knew that you had mentioned it at the moment of hesitation, he showed hesitation and entanglement. He doesn't know how to reply and how to choose. Does he want to leave the problem to time to solve, or does he choose to escape and solve your problem?
