I'm sorry Paula but in my opinion your husband seems to set you up. I mean he was the one who didn't come home. Since he knew what was happening HE should have called you to tell you about not being able to get home. If he cared about you he would have made sure you were not worried about him.
Also, just because he seems to abdicate his part/responsibility in the family's financial situation doesn't mean YOU are at fault or should take the blame. And since he said no about a local tax preparer/turbo tax, then IMO, he should be the one responsible for getting things to his friend.
I hate to see you hold yourself accountable/at fault for things that you are not solely responsible for.
