Relationships

Why does my crush seem to be upset with me?

ast year my relationship was in a bad place which made me a bit more open to other guys. At work I met a guy who I became attracted to and secretly had a crush on him. He was in a relationship too, I know that he knew I found him attractive and that I would get nervous around him because he became interested in me then really interested. I have always kept my distance but he did not. To keep a long story short he’s been very close around me, in a room full of people he’d always ask me about how my day has been etc. he even straight up asked me if I was single once. Looking back on it now I feel so bad about crushing on him in first place. We haven’t worked with each other for almost a year until recently and there is still that chemistry. I keep my distance so bad and now I think he might be upset with me. He was asking about my boyfriend and as I tell him he seems completely uninterested and annoyed yet he asks? Now of all sudden he doesn’t look at me or barley looks at me and I haven’t talked to him for a while. I hate going to work because of this, I feel like there is something in the air between us that needs to be cleared up. Please help? What is going on?
