Am I unable to feel hateful feelings? What's this called?

I used to be a very pionate person. I'd get jealous easily, go into rages, depressive states. But now, things that make me used to make me feel these, don't trigger anything in me at all. I can still feel, love or lust. I'm not very empathetic any more either. I kind of like it, if I'm honest. Is there a name for this?
