Basically there's this guy who I think wants to approach me at the gym. He always looks at me, smiles, etc. When I went to the gym this week, he didn't look at me, smile or anything. He always shows interest in me whenever I see him but this time, he didn't. Could he be insecure about my feelings for him or something? I have social anxiety so I probably haven't given him signs that I like him. I'm too scared to look at him or smile so maybe he's doing this because he thinks I'm not interested. Opinions?
