Why does he treat me differently when others are around?

There's this guy I go see at this small office within this gym. He massages my back every 2 weeks or so and I've known him for about a year now.

We became Facebook friends and he never comments or likes my stuff but we always talk about what we post up when I go see him.

For the past 6 months, I noticed that he won't acknowledge me when I see him around the gym or even if I see him right by the entrance. I felt awkward so I asked him why he does that and he simply just said that he didn't see me, which I find hard to believe, but anyway, I had an appointment on the night of Valentine's Day. We had like a snow storm and when I walked in his office, he was all alone. Usually, there are about 3 other staff in that tiny office.

He told me that he just sent the staff home since the weather was bad.

Him and I were alone and I noticed that he is so much more nicer and kinder when nobody is around. He smiled at what I had to say and I made him laugh. He even asked about my hair and if I dyed it and stuff and he said that he liked it, which he never says normally. I wish he would always be so opened like that with me. It was such a nice feeling. I sometimes wish we could be friends but it just seems so impossible.

Maybe he is not that interested in you.
Or maybe he is more of a private person and doesn't like the attention of people knowing whats going on in his life/business.
