Going out for dinner with my crush, help, im nervous!?

One of my best friends has just split up with his girlfriend of 7 months (he dumped her), he suggested that we meet up in the summer holidays so we are going to xscape and do the adventure course then for dinner. It's just me and him, he knows that I like him. Does he like me?he'd flirts with me all the time and always puts loads of x's at the end of messages to me, I'm really nervous and don't want any awkwardness at dinner, how can I make sure we have fun and everything flows well?thanks, were both 15 btw!x
