I fantasized/obsessed about quitting for years - even left my husband for a bit in 2015 because we drank together, so I blamed that dynamic.
He told me when Ieft that I would never be able to get sober by myself.
That pissed me off, and I finally had enough of the whole sick cycle, so on March 15 of 2016, I quit putting alcohol into my body.
It is a daily decision for me "today no matter what happens I will not drink" but now at nearly 9 months I don't have to say that in my head every morning and I am starting to move on to "I don't drink."
I am still with husband and son. Husband still drinks but not as much as he was - he appears to feel sheepish and will hide it (but I can smell it from across the room - ha).
It boils down to a very simple thing - not using your hand to pour the alcohol down your throat, no matter what. As Yoda says "do, or do not - there is no try."
