Personal opinion here, not sure if in line with DB thoughts. I have been on the receiving end lately of hearing about everything my W did...and it hurts. So if he knows already, don't open up those wounds again. No details. No excuses. For me, that would make it worse to have to read it and because it is in writing, I might read it more than once and play it over in mind...not good.
So Gutwrenching, as a person who is basically in my husbands shoes, would you say there is anything that I could say to make him feel better, instead of worse? He probably did read and re-read.
