You don’t have to be two junkies in a rehab house to have a relationship dependent on recreational substances. Sometimes, two ordinary, functioning people don’t realize that every time they are together, they’re drunk! They share a bottle of wine any night they stay in together. Weekend days are spent at happy hours or bottomless mimosa brunches. If you go out, it’s to a bar. Make sure you’ve thoroughly tested what it’s like to be together completely sober. Alcohol—even just a little—always makes other people seem more attractive, more charming, and you more horny and emotional. That’s the perfect, toxic combination for a relationship built on alcohol or drugs.
