Why do girls tell me everything?

It means that they like you and talk to you, which is a good thing. It means that this girl trusts you and trusts you. If it is the opposite sex, it is likely to develop into a confidante or lover relationship.

Of course, it depends on whether you are willing to help him deal with some worries. If you feel tired or troublesome, you can also completely refuse or perfunctory him. If you have a good impression on him, communicate with him more. Sometimes, more communication with each other can also enhance your relationship.

Have a nice day.
