Why are some guys such creepers?

Anonymous
there's a guy at my job who talks nonstop with other guys about how horrible women are, spies when i talk to other people, has asked me out once & never tried to actually follow through ( i didn't say yes by the way, cause he never asked me directly he just hinted as if he expected me to then become a man and take the lead). Then he is always randomly angry at me and accuses me of doing stuff to him (and he gets in my personal space and talks down to me). And one time he got jealous after assuming i was texting someone. Wtf? I barely even talk to him and yes you may think i did stuff to provoke all this... i didn't. Before all this i actually thought he was the most handsome guy at work. Now i see how ugly he is.
