I told my crush I liked him and now he talks to everyone but me. what is this?

There is the guy I met, he is my bosses son, he came to work for a few months. He's been staring at me for months, and looking away when I caught him, he only stares, and that's it. He initially used to joke with me via text and I included him in company activities. The staring didn't stop and I didn't approach cuz he made me nervous. Never the less, I couldn't take the anxiety so I caved and told him I had a crush, he told me he has a girlfriend and respects my honesty. Since then its been tense, I have told him I will step back and respect his boundaries. So I don't talk to him and pretty much ignore him, he avoids me and talks to everyone but me. He stares occasionally but looks away much quicker when he finds its me.
