Just to be clear, none of my relationships involved abuse. My first husband got sober the year before we got married, he never drank again, and we are still good friends. He's been sober 37 years. Our divorce had nothing to do with alcoholism--it was just a bad "fit." The second husband was kind and funny, but a seemingly-hopeless drunk who could not hold a job and was likely to die of alcohol-related causes. It was not a viable marriage.
And I think you are way overestimating the "stigma" of divorce. Most people barely think twice over whether someone is divorced. Your friends might initially be surprised because of what you posted, but EVERYONE puts their "best face" on Facebook. Don't ever believe everything people post about themselves and their lives is true.
