Instead of asking him out on a date, which is what I assume you mean by the first move, flirt with him. It sounds like the two of you are friendly. Now, turn it up a notch. Compliment him. Ask him questions about something — his food, his tee shirt, his work — get the conversation going…. so that he wants to ask you out. It’s always better to let the guy do the asking. Men love the chase, and when you ask him, first, you take that opportunity away from him. Also, you’ll be a lot clearer on how he feels about you if you let him do the asking. When a guy asks you out, he wants to date you. If he doesn’t, he’s not that interested. I know you’re excited about him, but see if you can focus on flirting and see what he does as a result. 😉
