Is it normal for shy guys to act this way if they like you?

I met a guy, who was very shy. Long story short, after about a month of working together I told him that I was "crazy" about him. He said that he thought about approaching me a couple of times, but didn't because he was there to work and wanted to focus on that. He said that was an awesome girl.. I thought that was kind of cheesy, but he says he doesn't just give compliments and saying that was vig for him. I think he was telling the truth about that. He also said that he was speechless, and he smiled alot as he listened to what I had to say.I thought I picked up on different signals that he liked me. For example, he would ask alot of questions about my son and the relationship my son's father and I had. He would also try to be around me from time to time. The day I told him how I felt, he said we would revisit the topic as it was getting late and time to go. I could tell that us living in different states was an issue for him. Although he never came out and said anything. When he went back home, we never talked about seeing each other or anything like that! We still talk from time to time because we have to work together. I can tell that he gets excited when we speak on the phone. I am just so confused about why he seemed interested before going back home but never said anything after the fact. He said a few times that he's a shy person, but if someone is interested, they would make an effort to see you....
