There are some ways that you can find out what you want to know legally without filing for divorce. What a ridiculous suggestion that is to find out what you need to know.
Have you gotten a recent copy of your own credit report? You never know how the CRAs list ownership of accounts until you look. While you can't get your wife's report you can certainly get your own. You entitled to a free report from each of the three major CRAs ((Equifax, Experian and TransUnion) each year by simply requesting it. You can do it online or through the mail.
In addition, you can join up for ID theft protection at any of the three agencies where they notify you of changes in your report. And maybe you could convince your wife that it would be a good idea if she did the same.
