Yoga,
Just want to let you know I made plenty of promises and really meant them at the time. There were also times when I had already been drinking that I said whatever I needed to in order to keep drinking. A drunk or addict can be as manipulative as needed to keep doing what they want. I never did this to hurt my partner, but I knew it did and that did not stop me. I told him he was better off without me. I meant that.
I did make a promise 300 days ago that I would not drink again. I meant it, like the many other times. But, unlike the other promises, I kept it. Sometimes we can heal, but in my case it had to be from within and for myself. There is nothing my partner did to force me to get sober. Once I made up my mind, it did help to have him keep alcohol out of the house and not drink around me for a while.
Good luck Yoga. You deserve to live a happy healthy life with a sober partner.
