Confessed to shy guy?

I confessed to an extremely shy and introverted but good communication skill type of person. He is extremely goal oriented that he had deleted all his social media and went lowkey to prepare for medical. He had always respected me, and I developed feelings for him and so I confessed. We don't talk at all. He said at first he doesn't know how to react, or he is afraid he'd break the door (when I said don't leave the door open), he said he's afraid he'd regret saying anything later, however after all this he kept on insinuating till the end of the conversation that it wasn't a rejection but he just don't want to address the situation or talk about it!

What does it mean?
