Blackfoot, thanks for your response.

I have always handled the finances in my M. I did it to feel in control, and H allowed me to do it. I would have no problem handling it if I were alone. H handled his own when he was single. If something were to happen to me, H would need to get up to speed with everything, giving him a disadvantage. He can just ask me for a receipt or important paper and I know where it is. I'm trying to make sure everything is organized so that he could find things in an emergency. I don't see this any of this as a sign of neediness on my part. Is it neediness on his part to rely on me?

The same goes for backing up files. I could certainly come up with a system for doing so. But, H has specific ideas about how he thinks this should be done. He is the IT professional. He's the expert. I figure that he gets paid to do this all day, so why not go with what he suggests. This is what I have tried to do.

Backing up files and handling finances aren't the actual problem though; differences in communication are the problem. Today's event just happened to be set off by my comment about backing up my file. The catalyst could have been any number of things.
