Being a snoop?

[lovethedove]

So this has nothing to do with my intending to snoop through his e-mail. Basically, I was at home and needed some tape so I called the bf to see if it would be alright for me to get some (he was at work). He said okay and told me where to look. It was when I was looking for the tape that I found something I really wish I hadn't. It's nothing pertaining to cheating. It's just really not right (it's more of an ethical matter). Do I have a right to confront him? As I am posting this dilema on here, obviously it bothers me b/c with what I found, it tells me he's been lying to himself, his family, my family, his friends, everyone for, well, two years. Would ANYONE here actually be willing to stay with someone if they found out their s.o. has been living with a pretty big lie??? Would you listen to their side and accept it?
