Search Results: friend insulting crush

I m a 21 years old girl, considered very beautiful. I m working as an intern in an organization. The coordinator for interns is around 32 years old guy. In the first meeting, i felt that he was a little attracted towards me, that gut feeling of a woman. And I also had a slight attraction and curiosity towards him as he looked exactly like my ex.
Anyway, moving forward. The internship went on and what me and my friends noticed was that he was extremely rude to me. Like he nearly insulted me once when I asked him for help for something, and when my friends asked him he was okay with them. He is crazily mean towards me which I don't understand why. I have hardly spoken to him and he behaves very angry and defensive in my presence, which others have noticed as well. He is very okay and easy with other interns but not with me.

I may assume that he is extremely repelled by me (even which is not rational, since I m a fairly attractive and easy going person. I always give smiles and hate conflicts). I m at good terms with everyone else.
The problem is that he looks at me a lot, stares at me and when he enters the hall, I am the first person his eyes lay on out of 150 people. He is always noticing me. Making eye contact but never smiles. My friends have noticed that he looks at me and gives orders. Like if he has to show his power being the coordinator and say 'Move fast!'. He will say it looking at me always.

Also, a little time before when I had a crush on him, I sent him a request on Facebook which he didn't approve and so I cancelled it.

What's wrong here? By the way, I didn't do ANYTHING in my senses that could anger him so much.
What is the reason behind this rage?
