How do you deal with a lowlife male jerk at work who can't even say hi to you?

And he can barely utter wors to you without a nasty attitude. Meanwhile with other females he acts the opposite.

He used to bully me at work by the way so i prefer no attention but the least you can do is say hi and control yor attitude. Like why does he have an attitude to a woman whos always nice to him and everyone? Im thinking he's just angry he knows he never has a chance with me but wishes he did. Cause i can think of other lowlifes at my job who were first hitting on me or nice then they either made a move and got denied or i wasn't excited about them and then they started hating me and being angry at every little thing i do or say.
