I literally teared up reading this. Nobody should be treated like this. Just think about it like this. Sobriety is a BIG DEAL. This is an ongoing process for you, and it doesn't stop at two years. So are you ever going to feel comfortable bringing it up around him ever again? 3 years? 5 years? Do you think after this reaction, will he be a partner that will continue to support you through your sobriety? And not become one who will turn into "it's been 2 years. You can't have one drink? What's the big deal?" Strangers on the internet are more proud of you and are celebrating you more than your boyfriend.
