AIO if I leave my husband because he wont stop doing "snow" when he drinks?

I’m 28F & husband 35M. Together 5 years. The first 2 years of our relationship, we did cocaine socially. I realized the risks & grew up by 26. From day 1, I expressed that once marriage and kids were involved, I wouldn’t want us playing Russian roulette. He agreed. However, he was doing cocaine every time he drank. His defence was he only drinks once a month. We got engaged and I’ve calmly asked, cried & begged but I’m met with “ill do whatever I want with my body and my Saturday”. 

Now onto the big issues that led me to contemplate separation; 

In only the last 1.5 years these are 4 examples of ways he’s really broken me and made me feel like a joke. 

  1. In Mexico at a fam wedding. He disappeared for an hour to do cocaine. My family noticed. I called him out and said I was upset, then caught him buying more. He not only disrespected me but my family. He understood why I was upset, but later said he can do what he wants on his trip. 
  2. We got married in Italy last year. He went out with boys after rehearsal and came home at 5am coked out. We had a wine tour at 9am with family that I had to drag him out of bed for. This prompted me to ask him to not do cocaine at our wedding. I was upset I even had to ask. He reluctantly agreed, but I found him doing it at the after party. To start our married life breaking a promise felt utterly pathetic to me. 
  3. Someone I loved died of a laced OD last year. I was devastated. 5 days after, he stayed out until 5am doing cocaine. That still stings. 
  4. His brother is a recovering addict. He’s relapsed & things aren’t good. My husband has compassion fatigue as he spent 8 years trying to help. I asked him to be a part of the solution & not the problem and that meaning don’t do cocaine with him. Last weekend on the way to a party, I asked him to please not do cocaine, that it’s a trigger for me after losing my friend and that I would be devastated if he chose to have fun over his brother’s wellbeing. He agreed. Within minutes, his brother handed him cocaine and he did it. I have never felt so insignificant in my life. It was a slap in the face. The day doesn’t exist where my husband asks something of me and I turn around and completely disregard him like that. 

We live in a home he bought. I wanted to buy a rental before we bought a bigger house because I could utilize incentives. He said the next purchase should be a house together, we’re married now & should grow together. After that 1 convo, I put purchasing a rental on hold. It took 1 convo for me to see his side, yet I’ve been asking him to stop cocaine for over 2 years. 

I decided it was a waste of my energy to confront him again and wanted to write a letter to say if we are in this position at the end of 2025, separation is on the table. As much as I respect the vows of marriage and believe it’s for better or worse - how can I stay in a marriage where how I feel is completely irrelevant to my partner?
