hi nwnewstart and

alcoholism and BPD can each make for a pretty volatile relationship. put them together, and you have a pretty mean cocktail that exacerbates traits of the disorder, and the two issues fuel each other. unfortunately this is not uncommon, and im very sorry to hear you experienced it .
a frog in the pot is a good analogy that i think many of us can relate to. presumably all of us had the best of intentions. it sounds like you gave it your all. thats something to be commended for.
how is the sporadic and inconsistent communication going? you say you are separated and trying to untangle yourself emotionally (that must be hard); whats the status of the relationship?
