What does it mean that my girlfriend can't delete or get back the information after breaking up?

If a girlfriend doesn't delete or return the message after breaking up, it may have the following meanings:

1. She is angry with you: If you just broke up, she is probably still angry, hoping to get your attention by not deleting WeChat. She may want you to coax her or she may want you to change your behavior.

2. She hasn't completely let go: after breaking up, it is sometimes difficult to completely let go of her feelings for a person at once. She may still like you, but she doesn't want to show it now, or she's not ready to face you.

3. She needs alone time: Sometimes, people need some alone time to re-examine their lives and think about their future. She may want to keep a certain distance and give herself some time and space by not deleting WeChat.

In either case, I suggest you calm down and give her some time. If you are sure that she still has feelings for you, you can try to communicate with her at an appropriate time to understand her feelings and thoughts. But if you find that she has completely let you go, then you should also respect her decision and don't struggle.
