Why the hell can't I hate this guy!? I need some advice in this situation.

Ok, so I know it's good not to hate people. It sounds odd, but I really should hate my ex. Here's why. When I was 19 I knew this 'cool' dude. We got together. He was 33 then. We liked to take drugs. I got pregnant, gave up everything. He wanted the kid badly. Here's the deal. Over the past 5 years, this guy has pretty much been the dodgiest guy I've ever met. But I can't hate him. Here's a list of the things hes done to me:

• controlled joint finances. Spent all our money on heroin, pretending to work, while I stayed at home caring for our child. I wasn't on anything, and was in the dark about this. He said work was slow thats why we were struggling to get food. My money went on his habit.
• gave me herpes. Yeah. A precious lifelong gift there. Thanks buddy. When I found out he tried to blame me for it - I'd think you'd have noticed, it's your fault. I didn't know he had it. I trusted him.
• I then found out he had contracted herpes from his 'bosses' wife. His boss at this job btw was the one supplying the heroin. He still won't admit to it, even when she told me and apologized to me.
• when I left, kept the house full of furniture my parents had helped me to get. When I went to get it back, he'd sold it all.
• told lies about me when I left him. I had people who were threatening to kill me over this stuff
• he has a 'fake' life. He's so good at keeping secrets that some of his 'closest' friends don't know about his habits/past.
• I didn't find out he'd spent time in prison until after I left him. He robbed a house and nearly beat the owner to death.
• I had to move hours away to stop the harassment after we split, he then took me to court over custody of our child, which he nearly won. (failure of the family law system right there.) The list goes on, and on. But I'll leave it at that. My problem is, I literally can't hate the guy that has given myself and our kid hell for the past few years. Why!? I know I should. I don't love him by any means, but I can still talk to him and we get along still. Should I hate his guts? Or am I lucky to not feel it?
