my wife left, but still lives with me

[MrBond]

Right now the only thing I notice in your post is a lack of passion in wanting to fix your M. You question the process and "success" but you haven't given details about what you actually changed and if there were other issues that your W actually discussed with you.

Is this the first M for the both of you? You aren't being a doormat. Your W just says that she isn't "feeling it" and you're taking it as her doing something to you. She's not. She's just going through the same thing many couples go through. Have the two of you actually lost touch with one another?
