being in "business" with him is like having a first class carriage seat on a runaway train. i'm sorry but your business IS suffering and HAS suffered ever since the active alcoholic was given any level of responsibility and funds management. as i suggested prior to your departure, i sure hope you have a good solid Plan B in place, because plan A is failing.
it's really time to quit expecting him to behave like a regular/normal partner, or even adult.
