Honestly, there might not be one single thing that makes your W take notice. If other women are noticing then clearly you are doing something right.
Sometimes a WAS is simply done. My H was. Of course his affair helped him along but no matter what, my H was done. As I have said before NOTHING made him think twice... not illness, legalities, a trial or losing all his assets made him blink.
If you feel good about you and the changes you are making then stay on that path. If your W takes a second look, well, GREAT! If not then you know you are on a healthy road to rebuilding a new life for you.
