So can you really hate someone that easily and just treat them like they are worthless?

Reminds me of the old Krishnamurti quote:
“You say you love your wife. You depend on her; she has given you her body, her emotions, her encouragement, a certain feeling of security and well-being. Then she turns away from you; she gets bored or goes off with someone else, and your whole emotional balance is destroyed, and this disturbance, which you don’t like, is called jealousy. There is pain in it, anxiety, hate and violence. So what you are really saying is, ‘As long as you belong to me I love you but the moment you don’t I begin to hate you.”2

In your situation, he was just lying to get to you. I think we've all had an ex say something like that when they realise they won't get us back. At the time, he loved you but he was venting his anger in a negative way.
Personally, I can hate someone within 5 minutes but I couldn't genuinely hate my boyfriend in that time frame.1
