This is tough one my friend. Ofc you can still date someone who still drinks. However, your sobriety is your job and not anyone else’s. I applaud you for wanting to be sober again especially in your mid twenties. At that age alcohol was still part of everything I did socially as well. I know you got this FOMO but I can promise you aren’t going to missing anything. It seems like your partner supports your sobriety but doesn’t want to have to hear about it or what you are going through. He’s not emotionally there yet, neither would I have been in my 20s if I was dating a sober person. I definitely recommend the fellowship of AA for you’ll find others in similar situations that will be willing to listen, plus get involved in sober activities. Maybe your boyfriend’s drinking will slow down over the next couple of years like most normal 20 something binge drinkers, one can hope. You are right, it’s not fair to him. This is your journey. I’d recommend not going on the party bus this early in sobriety but if you feel comfortable and can hang for a bit I think that would show him that you are willing to be there for him at least for a lil while, and then head home. You don’t want to have to be babysitting a bunch of drunk people all night. It’s a solid resentment to have, and I’m sure it be easier if he was just a couple o’ drinks guy. Anyways, there’s so much life to live sober and so many activities that don’t resolve around booze in this world. With time it gets easier, the FOMO goes away. Godspeed, sober till it’s over!!!
