Thanks everyone for the input. Still haven't decided what I'm going to do about it. We have discussed our finances but she doesn't work and owns nothings but clothes. At first she said she was looking for a job and then decided she wanted to be a house wife that maybe goes to school for now. I thought about it for a while and decided that's alright, but then decided on a prenup, which she changed her mind about it after the engagement. She has a general idea of my finances which are stable with considerable retirement and savings for someone who is 33. I told her a personal monthly budget for her I could afford, and since I have two cars said one would be hers. Since she has no history of being responsible with money, changed her mind on the prenup, and keeps asking for expensive things, I had decided she doesn't need to see all the details of those accounts.
I know there are lots of differing opinions but I believe what's made before the marriage should be separate in case of a divorce and everything after shared. Despite that I was even going to put her on half the house that I own in full. After changing her mind on the prenup I think her curiosity got the best of her about exactly what I have along with the questions they were asking about her. Her intentions are still not clear though, does she want to know so that when she asks for a big purchase like 3k for Invisalign braces or trading in the car for one 10k more, I can't say I don't have the money as an excuse? I do say that when it isn't true, but that's because I'm not making that much, it would have to come out of savings which I don't touch for things like that unless necessary. I'm not really sure why she did it.
Ignoring all the financial discussion, she did not have permission to access that computer or email account, and forwarded all my financial information from my secure email address to a free one of hers and a ex-coworker of mine on accident. I don't have access to her computer, email accounts, phone, or anything like that, and she doesn't want me to.
