She has been nice and hasn't started any fights but still it feels like she is getting farther away.
Maybe she is getting farther away however this is the right path. This is the only way you MIGHT get your marriage back. She is going to test these changes you have made, to see if they are real. Right now she may not believe them. Sounds like you don't believe them either.
Its OK to fake it until you make it. However you must make the changes for real.
