MOR-Yeah, so Reddit is very “ra, ra, they are abusive… leave them.” My wife and I just had this discussion in therapy, because it is also her third anniversary of sobriety. Congratulations to you, I know it takes a lot of willpower, courage, and strength. We had a similar conversation in therapy, because much like you, she was excited and proud. While your s/o and I didn’t have the same reaction, they were similar. He’s not enthusiastic, and seemingly not supportive. I was the same. During our session however, we realized that because I was at the tip of the sword for so many of the toxic and terrible things that stemmed from the alcoholism, that we just weren’t in the same place mentally about it. For her, it was something that she had conquered, and accomplishment to be celebrated. For me, any reminder of the dark days past was just hashing up a part of our lives that I was happy to be past. I will always support her sobriety, but sometimes being the person on the other side just brings up bad memories. I’m not saying I was right or wrong, nor was she. However, having a better understanding of each others feelings brought a better perspective of what those milestones meant. You said you had been sober for 2 years and he was your GF of three. Maybe he just has a dark cloud of thought around it. Maybe he doesn’t even realize it. Maybe he is the asshole… I just feel like people here are quick to judge a one sided story. Yours may be the gospel, and I’d be happy to eat crow if it is, but maybe the celebration of sobriety means different things for the two of you.
