I know it is incredibly difficult, and requires a huge amount of restraint - but they are right... it is best to keep it "business-like".
This is especially important when you go and meet with a mediator, or attys, or the judge for the divorce. It does YOU great service, and goes a long way to adding to the discrediting of the AH. (Been there - done that).
All during my proceedings, I so wanted to scream out the details of just what he had done, how it ruined our lives - but I didn't. Instead, I let the facts speak for me. It was all there in black and white.
You can be assured that the attys, mediators, and judges KNOW that the problems didn't cause the alcoholism — but that the alcoholism caused the problems.
