My drinking almost ended my marriage. Made it as far as signing divorce papers. It was the slap in the face that I needed. Losing my husband and step children wasn't an option. I convinced him i could be better. He said if i make it to 90 days sober he will burn the divorce packet. Im at 69 days. The 90 day mark is 3 days after our anniversary. Im hoping to have an anniversary celebration and ritualisticly burn the packet. I havent slipped but i still think about going to get it every day. Does that ever go away?
It does go away. Do you work a program? It was definitely easier for me in early recovery to go to meetings and work the steps. My first stint of sobriety was on my own. That feeling was there for years. I white-knuckled it for over 10 years before I relapsed. I wasn't in recovery, I was a dry-drunk. It was miserable. I highly recommend a fellowship of some sort, whichever one(s) you want.
It does go away. Stay active in recovery and get a sponsor! 
69 days is huge. The thoughts don’t mean you’re weak.. they mean you’re rewiring. It does get quieter with time.
I love the idea of burning the packet intentionally. I’ve done burn rituals in recovery and healing.. they were powerful for me. Let that fire represent release and commitment.. not just to your marriage, but to your sobriety.
You’re not alone in this. Keep going. 
Stay strong.
