How Can I Not Look Dumb?

I work in a big store and we have a very good relationship with most of our colleagues. This summer, a colleague from another city we have known since last year came. Then our relationship was purely friendly, but this year something happened, I can't explain it. Suddenly I began to feel something other than friendship. One of my colleagues was constantly joking with us, and I was annoyed at first, but then I realized that many of the things he said were true. And I don't think the man in question was indifferent either. At first I thought it was all a coincidence, but then I started to think that he also has some feelings for me, I don't know exactly what. We were constantly talking, teasing, but at the same time it seems that he cares about me and this obviously impressed others around us. Before he left for his city, he took my phone and told me when I wanted to call him. Since he left, and it was the end of August, I have not called him once on my mobile, I only called him once on the office to tell him something related to work but also to hear him. Yesterday we talked to this colleague who was talking to me and my man called, they talked and asked to talk to me. We talked a little and then as good as I felt, so bad, because I was dumb that I couldn't see him. I really want to call him, but I don't know how he will react and I'm already starting to think that the distance stops him the most, because that's how we'll both suffer, but I still don't stop thinking about him no matter how much I deny him and don't I know if I should call him, when will I be scared ?? I only called the clerk once to tell him something about work but also to hear it. Yesterday we talked to this colleague who was talking to me and my man called, they talked and asked to talk to me.
