Do you suppose it might be because he feels "out of control". I know I do when things keep going wrong. My husband lost the transmission in his car last weekend and had to take my car this week (he works out of town during the week), and I was a little overwhelmed at the cost to repair the car or worse, the cost to replace it. I just cannot afford it right now. And today I have an interview about a half-hour away and have to take a taxi, which will cost me close to $100 with tip. All the car rental places are empty because we had a huge storm last week and the cars are out to people with insurance claims.
My point is that if this overwhelms ME, how would an active A see it.
I think you are doing a great job, just working around his anxiety and getting things done. He will probably calm down once the repairs are finished.
I don't know if this helps, but I could just relate to the feeling of "powerlessness" that these situations can bring.
