I'm really at a loss of what to do about this. I left a game open on my computer so it didn't lock and went to take a shower. My fiance went on to my computer and went through my email. I was discussing a prenup with a family lawyer though email, which we had talked about, but then later she said she would never sign one after I started the process. One of the emails had a Word document for the financial disclosure with all of my bank and investment accounts listed. She first accidentally forwarded it to an old co-worker of mine with a similar email address to hers, luckily it looks like it didn't go through. She then forwarded it to herself properly and it did send. I found out shortly after I got out of the shower because I got an undeliverable message for when she sent it to my old co-worker. She then owned up to doing it and showed me her email accounts on her phone, but since I didn't see her delete it I'm not really sure if she still has it saved or has forwarded it on to someone else, or even another email account she has. I'm really not sure what to do about it. It sounds very illegal to me but I'm not an expert in that area. Not sure if I should report it to my bank or what I should do. I took her home to her parents house where she lives as she begged me not to tell them what she did. I haven't decided what to do about this yet, or what I should do.
