Birthday!!!!

On Friday I turn 16 and I'm so excited. I hope my boyfriend can be there but I'm not sure because he isn't answering me. I want everything to work out but I just don't think he's gonna be there for my birthday and it's my sweet 16. It's kinda big for me and I hope he doesn't miss it. Should I keep calling him daily or should I leave him alone? I mean I only call him once daily hoping that he'll pick up but he doesn't and he doesn't answer my texts or anything. I'm excited for my birthday on Friday but I'm sad because he isn't answering me.
