Dp, I am completely with you on not being able to shut my mind off. I have always had trouble sleeping at night, even during good times, because my mind does not stop. I can be exhausted but lay in bed for hours. Marriage troubles do not help in the least! I have taken more sleeping pills this past year than I can count. I almost hope to catch a cold so I can take nighttime cold medicine to knock myself out. There are no easy answers to help you sleep and calm you mind. I would recommend a glass or two of wine, but that in itself can lead to other problems down the road. I have found that watching tv, especially shows/movies I have seen a million times helps. I do not have to focus on them (or I will be awake all night watching tv) but the show causes a distraction to keep my mind from starting up.
As for what your W told your friend, ignore it. Remember, believe none of what they say, and only half of what you see. Your W is still in the stage of justifying her actions. She is not ready to rebuild your M right now, so why would she say anything other than what she did.
I know it stinks to hear this, but you have a long journey ahead of you. You are just getting started.
Keep your chin up!
