Agree with Huddy 100% , you've apologised so stop now You keep saying she refuses to work on it , are you still asking her ??
G , this is going to be ok for you with or with out W. Your going through a tough time but look at the positives for you. Your healthier , slimmer (. Huge congrats and very well done ) and you see your part in M breakdown. Move forward from here That's done. Become the very best G you can and if W doesn't want you then her loss mate
Acceptance is key and fake it until you make it. Each day is a day G decides how he will feel NOT W by her actions or words
