How long are you angry after a breakup?

I'm just curious about some other people's experiences.

It's been almost six months since my last breakup, and I haven't seen him, talked to him, written to him, heard from him, no contact whatsoever! And yet, I'm still angry when I think about him. Is that normal? Shouldn't I have gotten all the anger out of my system by now?

So pray tell... how long are you angry for after you break up with someone?
