Guys or girls?Some help pls...(:?

So my bf hasn't texted me since 7 this morn & its 1am now.Should I be worried?He wants badly to meet me tmrw but I can't,I didn't reply his last text at 7 when he asked if he could meet but usually if I don't reply for long,he always texts again or call...should I text him tmrw morn first or just wait for him?Thx guys!
