I normally don't condone snooping and I'm not condoning snooping here either, But dude your level of privacy is fucking ridiculous. If you have skeletons in your closet, maybe you ought to get rid of them. And not only that the person you're going to marry one day is going to want to know that weird shit about you. And theyre going to be okay with it. Clearly whatever weird shit you were into doesn't bother her. Or she would have already broken up with you. If these habits you had were so damaging and you're so hell-bent on keeping it a big secret I'm not surprised at all that she went through your shit. You pretty much brewed the concoction for her to do so. I can understand privacy but dude you're trying to protect parts of yourself you're afraid to show to other people. That's not privacy that's hiding who you really are.
