Cally, certainly a spouse can go get an insurance card out of the other spouse's wallet without it being considered snooping. My W does that all the time and it doesn't bother me (although when she leaves me with less money than I thought I had it can be annoying). I'll go through her purse to find stamps. It is to be expected when you share a life that circumstances will require you to go through their things for various reasons. His defensiveness is a bit unsettling. IMPO he either has something to hide or perhaps is trying to get you to wonder what he is up to in an effort to shake things up in the same manner as when someone here (Chrissy maybe?) would leave brochures (sp?) for apartments lying around. Is there a chance he thinks that you take him for granted? That you are not willing to meet his needs no matter what and he thinks you think he will just live with it? I'm not saying that this is the case, just perhaps another reason why he would do this. After all, a wallet is not the most inconspicuous place to keep a condom. The telltale ring (that was the main reason we guys carried them in school) gives it away.
Gone the carvings and those who left their mark. Gone the kings and queens, now only the rats hold sway.
