The ex-girlfriend texted her ex-boyfriend to ask him how he was doing. The ex-boyfriend said to her ex-girlfriend, can you reassure him? What do you mean?

Let's put aside the external environment of your boyfriend's reply to this message and his psychological state at that time, because generally one sentence can't explain anything, maybe two Chinese characters have no special meaning but are inadvertently said. According to common sense, this sentence means: "You can't be friends after breaking up, because they hurt each other, and you can't be enemies after breaking up, because they loved each other, so the two people after breaking up became the most familiar strangers." Both of them have their own life circles. What he means is that you will leave me alone in the future, okay?
