A red flag jumped at me as you mentioned your court date is set and your W wants to know what you feel was your part in the M failure.
This is not mind reading, simple caution. Be careful about putting on paper anything that might show you in negative light if brought up to the courts. Even if it seems benign to you, it could be twisted out of context and used against you as leverage.
IF you write anything, suggest the learnings, rather than the negative behaviours.
ie. "I told my parents that I've learned we have two ears and one mouth, because we should listen twice as much as we speak" As opposed to saying, "I nagged and complained to my W all the time and realized I never listened to her."
