I don't have any advice as I never made it to this stage, just wanted to say it's good to see you're still being strong.
I know it has to be frustrating, but you are controlling the only thing you can, which is you. You're wife is moving at her own pace, but I hope she soon begins get the motivation/inspiration to begin to make the changes she needs to make. Keep doing and showing her your best no matter what though Jon!
