If you're "done" be done..no need for "burning" anything. Walk away and heal yourself,then move on. For me it's easy to blame his drinking(just like I did for my ex's).. At the end of it all, I was the one to blame for what was MY actions/reactions to her/them. Took personal owership of myself for that and got 'better'.
Also: that Tomsteve link is 'on point'..as an ex drunk myself and a master manipulator..it's best to 'walk away' and mean it, if that's your plan(no pics,no 'closure',just walk/run). NO CONTACT...but, just like I tell the newcomers in the drinking forum..that's 100% your choice,so own that decision.
