How did you get married and not address this? Did she hide all these figures and change her behavior? Would I be correct in guessing you were financially established and she wasn't? I'm just guessing that your wife omitted her past and either hid or repressed her behavior to seem like a more suitable partner.

The reason I'm making these assumptions she must have been living this kind of lifestyle long before she met you with numbers like that. So why did you marry her if it bugs you? I'm sorry but I don't think she will change and from what you've said she doesn't want you involved in that side of her life. So you either come to peace with it or move on.
