Hi. Just to weigh in behind Sandi , your W walking around like that means nothing. You trying to analyse it will only wreck your head. Look at this this way , she's doing it because she's trying to tell you something OR look at it as she sees you as a good friend with no sexual feelings for you so she's very comfortable dressing like that
My W was in my bedroom sat am wearing nothing but my 14 year daughters very short ( for my D , let alone my W ) dressing gown What I took from it was .......... Nothing
It doesn't matter Focus on you and living your life. If your W wants an R talk she will make it clear
My personal analogue for this type of thing is your looking for a planet and your staring into space and all these stars can be see. but they are not the planet your looking for. When and if the planet comes into view it will be clear and not to be confused with the Stars
