Late replies & desolated phone calls

I called my girlfriend for like 5 times? She didn't reply. I text-ed her. She replied late. She told me she was with her best friend talking. TALKING?! YOU WERE TALKING AND YOU COULDN'T REPLY ANY OF MY PHONE CALLS?! I was so freaking mad. I tried to be understanding, "She hasn't met her best friend for quite some time. Let her spend time with him" BUT AT LEAST ANSWER ONE OF MY PHONE CALLS!? *sigh* I really love her so much. I guess I should just be understanding and let this past.
