Im really lost

Hello world !!!
I've got a friend who used to always call me or vice -versa.
But last week, we had some misunderstanding;
from then on she is not ready to speak to me at all.
I tried calling her and explaining but to no avail.
She has asked me not to call her from now on.
Im really lost. Without any fault,
she is behaving as if I've commited a crime.
Dunno what to do. Any suggestions folks ???
Have a nice day !!!
Cheers !!!
