Marriage doesn't require complete and total knowledge of your S.O. But, depending on how long you were together before getting hitched, it's pretty normal to end up learning more about your partner once you're married. We'd guess that, usually, these revelations tend to be more mundane (your weekend habits, the true extent of your jeans collection) than earth-shattering. At least, that's how we hope it goes most of the time. Of course, some people end up harboring major secrets from their loved ones, lying to them well into their marriages. These secrets might have started as white lies that simply grew over time. They may be omissions that never came to the surface on their own. Or, in more serious cases, they might be hard-to-accept truths that have stayed hidden to avoid hurting anyone. Even though these secrets mostly remain, well, secret, some people have posted their marital lies (and more) to secret-sharing app Whisper. Ahead, we've rounded up 15 of the most shocking lies people have told their spouses.
