So obviously you’ve made a huge mistake, but the next wrong move would be to listen to any random Redditor’s advice because they don’t have the same stake or interest in your relationship that you do. Most people on Reddit would like to see someone who cheats or makes a mistake have their entire life ruined as a way to “take responsibility”. Sure you’ll have to tell your wife at some point, but fortunately life is full of possibilities and your relationship doesn’t have to end over some drug fueled infidelity.
