Well, the guy I am currently interested in is definitely into me. However, we wouldn't get very far if it weren't for my checking in with him from time to time. Let me tell you, I start to wonder if he isn't really interested after all, maybe I said something, etc, etc, but then I contact him, and it's perfect again. Now, I am not usually forward like this, and am old fashioned, and let the guy make the first move. AND, I'm definitely not a dating expert. However, what I would suggest is this.....Just drop him an email saying you just wanted him to know you had a really great time and you're looking forward to getting to know him better. Simple, not over done, not pushy. If he's truly interested, this should give him the nudge to call you.

Just my 2 cents....
