I haven't gone too far have I?

The company I work for is having its building remodeled. The field manager for the company that is doing the remodeling has been in the building for about the last 4 months. We saw each other here and there, but since started chatting. He passes by my office more than he needs to, which I like and our conversations have become more personal. But it hasn't gone beyond that, which is fine for now. I like not following each other on social media, not texting or calling. It's like an exciting high of just enough flirting to be fun. However, I sent him a few emails asking about the building project, first REAL questions then a silly one. Which he thought was funny and responded comically. But I sent another silly one with no response. I'm worried since we really don't know each other he doesn't get my humor and it's one too many. I will see him around the building for a while and don't want things to get weird. I want the playful, flirty, silly banter. I'm afraid I've already ruined that. How do I back it up so HE emails me or HE stops in to talk to me? I can't email HIM again that's why got me where I am, feeling that I went too far.
