Opening the door

So...I had some errands to do at lunch today which just happened to bring me right across the hall from High School Guy. I really didn't make up an errand just to go see him - my hairdresser is across the hall and I need some product. All right, need is perhaps too strong a word. However, I emailed HSG to see if he'd be there if I stopped by. He was and I did. We had a nice, but unfortunately non-flirty chat. He did say we should get together this weekend though. Then as I was leaving I threw caution to the wind and turned it up a notch. Since he knows all about the dates I've been on I told him I had rejected three of the six people I'd seen recently and didn't have any dates scheduled for the foreseeable future. Then I told him I had three people on the short list. And that he was one of them. He smiled and seemed flattered. I should have said he was my number one but I didn't want to scare him. I need some advice folks. Lay it out on the table and risk freaking him out (it's only "like" though so how scary is that?) or keep it to myself and explode hoping he'll get my hints. This is your time to shine oh my peanut gallery. Let 'er rip!
