no respond

My boyfriend hasn't texted me since 7:50 it's about to be 11, I called him, FaceTime him, text him 4 times. The last thing he told me was he was doing a cook out outside his place with his roommates. I'm overthinking maybe he went somewhere else to drink with his friends or something): should I let it go? Or just wait until he texts me? He might text me tomorrow "I fell asleep" I just don't know what to think.
