I have started to keep a diary in my cell phone. I document quality time with my kids - if my w ever tried to call that into question, and I document erratic behavior by my W in case our D ever turns (more) sour. In this day and age having a indelible record is pretty easy. I am not perfect at it, but it's a START. I doubt that this BB is admissible. Even writing on good old fashioned paper may be more reliable.
