well it lasted from 8pm till 2am, because we needed to get up and work the next morning, so we had to go back, otherwise it would lasted longer.. we didn't end up in bed, he needed to drive back home after some alcohol. He sent me a text saying that he had a great time, I reply I also enjoyed it. But then we didn't message again, now it's already one day later. I think we should wait a bit longer to text each other? I don't want to play games, I hope he neither, but everybody has a life, is it?
