Is it the default to break up and not return text messages?

First, maybe she doesn't know how to reply to your breakup message. How to reply to you is really a very tangled thing. If I hesitate for a long time, I don't know how to answer.

Secondly, we have reached a consensus that there is no need to use too many words to express and describe the relationship between two people, the end of a relationship? It must be caused by many factors. There's really nothing to say in the end.
