Why hasn't he replied my text?

I hit it off with a dj who works in the local club, we had sex after his shift and got on really well. He pushed away a grl that tried to kiss him infront of me. He sent his family to where I work because I work there apparently. I text him all night and he replied until i asked if he wanted to meet but heard nothing. He apologized the next day coz he was ill and stayed in bed. I said me and my friend were going for a drink so hm and his friend came. He occasionally checked out other girls infront of me but hes single he can do that. He has a bit of a male slag reputation but hes popular and good looking. He said to me he wants me to come to his gigs and go in the box with him which must be a good thing. We were just chatting and then at the end asked if i wanted to stay him. We went back and i wanted sex but he claimed i only want him for sex which isnt true. We still did it and i stayed over til the morning. WHen i left, he blew me a kiss and said "text me", so later on today i sent a casual text but heard NOTHING. Have i blown it? why hasnt he text? I'm going to his gig tomorrow and im scared hes going to tell me to go away! help! what to do......
