How to tell if someone blocked your number? (iPhone 5)?

I was texting a girl I met at the beach. We was really getting alone. She said she liked me. She even kissed me out of the blue one night. But then one day my iMessages stopped delivering. I tried calling but all I got was "We can't complete your call at this time. Try again later." Her phone could be off and I could be over exaggerating but i really like this girl that's why I'm asking.
