Corri, I was laughing so hard at this post. Good for you!
I have had similar "call the insurance company" exchanges with H also and eventually just told him to either find time to do it at work or let me handle it and then accept whatever I told him. I especially loved the "I can't either" response!
This whole exercise in planning the spa weekend will be good for your H. It will boost his own sense of contribution to his wife (an important factor in feeling like a good mate, right) as well as lessen his dependency on you to take care of everything. A two-fer, yeah!
Have a great time and if I am still around when you return from your weekend, I will be searching out the nearest bridge from which to hurl myself.
