How can I tell if I have been blocked from a friends phone. Long story short, this girl and I are friends and we haven't been talking to eachother for 4-5 days. The last text from her was on Wednesday afternoon of last week. Now I have been trying to get a hold of her these last few days and nights. She hasn't responded to any of my messages. I checked the message details and it said that the messages were sent. How do I know she got them or not? Or had she blocked me from texting her?
