My crush is avoiding me after I asked him out to meet outside of work place, did I turned him off?

We are both teachers. He is an senior by 4 years. I thought he liked me because he always initiates conservation & use my name so much then he does with others coworkers.

I like him so I ask him to meet me outside & he said that he is busy after he took an hour to reply. The following days in the work he avoided me by looking distance & keep talking to peoples then he left without ask me why I called him. He avoids meeting my eyes. I feel heart broken. I will never confess to person after him that shit hurts.

Did I turned him off? Did I seemed so creepy? Should I gain his attention because he avoids me now.
