I snooped on my DH's email. I know that is a big no-no, I have no reason or excuses, I am a just a nosey person. I saw something that I wish I hadn't seen. An email from an ex-gf who I have never met and who I thought he hadn't seen or been in contact with for 6 years. It spoke of being grateful that he'd been in touch and how much she had missed him. I don't mind that he is in contact with her, but want to know why he hasn't mentioned it. I am desperate to know more about why he has been in touch with her, but obviously if I mention it he will know that I have read this particular email. I can't stop thinking about it. What should I do?
