Is it mean?

This girl is online on WhatsApp hours every I texted her a message. I texted her a message once every hour for 2 hours.

After that I said I am going to a place and she replied instantly : where are you going?

And I replied where to I am heading.


Later that day I asked her why she only replied on the last message,

She said: I wanted to know where you are heading to.

She doesn't reply to anything else, not even good morning, good evening etc.

Is her attitude mean?
I got really devastated and wanted to cry.

Btw: She said the day before that we have a future together and that I am important to her
