This is happening and it's very very sad You can carry on and that's your choice or you can decide to change and move forward. Your weight loss sounds great and is a huge positive.
If your W ever does turn around then it will be a long time and that's hard to accept
Think of it like a dog that's kicked every time his master comes home and then the master stops. How long before the dog really trusts that the changes are for good ??
Your W has a picture of how her life will be when you separated. She is not going to change her mind until she lives this reality
Ghost I feel your pain but accept what is a move forward for you
