Hello Jam,.. my friend here had experienced the same thing before, her boyfriend had an accident and was not able to leave any message. I know how it hurts. I am not saying that the same thing might have happened to your bf, maybe there are some circumstances that can't be avoided. You said you have emailed him and wait for a reply this Friday, just wait for it and don't stop praying. Have you tried calling him...? I don't think its the right time to give up and say start moving on. Just trust in his words, and lift it all to God. Ask some signs.
