I'm not even sure I need advice, maybe just to talk this out a little. I don't want to talk to anyone IRL about this. My sister's boyfriend used my computer, left his email logged, and I went into it thinking it was mine. There was an email from a dating website (Honestly when I saw the subject I opened it because I thought I must be in my FI's and freaked a little). Then I saw his name and freaked out and logged out right away. Now I have to tell her this but I don't really have a lot of information because I closed it so fast. I feel like I am going to puke. I know that I have to tell her this, I just have no idea how to do it.
