Thank you for the advice - I can promise you my heart is very much invested in saving our marriage if at all possible.
My changes haven't been to get my W back - although that was what bought me here originally thus while scenario made me take a hard look at myself. They are changes that I realised I had to make myself - whether my W returns or not could or would simply be a bi product of those changes.
