Can we send messages to each other after breaking up?

I think it's ok, but only if you have this person in mind. If not, I still suggest not to send it. After all, you once loved each other, and you need a cooling-off period after breaking up. Relatively speaking, girls may be sad, and boys will have a longer love arc. Therefore, it is really not recommended to send text messages to each other when the two sides have not completely let go, but if you have let go of this relationship, it is ok to send text messages. After all, a lover will not become a stranger until he is full, and he can become a friend after he puts it down.
