Is this cyberbullying?

Well, I really think it is. Next time you get a text. Delete, and break your phone. And do what I do. If they talk to you start laughing. And then In the end they'll end up saying sorry, or you might. But i would NEVER forgive a "best friend" for doing that. You really don't need them. Find other friends. I'm sure you have SOO much more! You have the same problem that i had! Hope this helps!!!!!!!!!
