Seeing an old crush??

So I'm going to be seeing this guy that I like at a party soon. We used to work together and when we did, he flirted with me a lot. He was really sweet at times, and he layed it on thick that he wanted to hook up. But when I gave him chances to make a move, he didn't. So now I'm going to see him soon and I want him to realize what he missed out on! Any tips/suggestions?

I think you should just be yourself. There are any number of reasons he didn't make a move last time, including the fact that you were coworkers. If he really likes you, and he is available, he will pursue you.
