This is where you must understand that emotional attachment and GALing is not for the benefit of your other half - but for you. It will help you create a mindset where you are able to interact with the world and H with your own needs in the front of your mind and not trying to do or say the 'right thing' to please your H or what you think will 'fix' your M.
If you try to play games with his mind, I feel that eventually you will slip up and reveal your truer self - and destroy any advances you have made.
If you make these changes for your benefit, then you will be more likely to stay true to them. This has a double win/win side.
1/ If you still D, then you will have moved on and will be more able to heal and find other happiness.
2/ If you don't D, then the changes will have worked in saving your M, but also you will also be able to build a stronger M, and you will be a more confident and stronger person in yourself.

Cause all of the stars, Have faded away, Just try not to worry, You'll see them someday. Take what you need, And be on your way and, Stop crying your heart out.
