Still pissed after all these "I'm sorries"

What do you say when you are still angry and resentful toward someone who has sincerely apologized 1000 times already?

I'm sitting here on the phone with the IRS getting to the bottom of all the taxes Husband didn't pay while he was in the throes of his illness, some of which could have been handled if he'd skipped a few visits to the $500 prostitutes.

I'm so angry to be in this position, and so angry about the lame way he's handled resolving these issues. He is trying, and the deeper into recovery he gets, the more honest his efforts are. And he is sorry.

But I'm still pissed. I don't want to dump all over him because there's little he can do. The past is past, the mistakes have been made (and they weren't all his, because I could have paid more attention.) So I guess I just air out here and move forward?

I know! I'll make an outreach call! (I never do this, so it's a good contrary action.)
