C,

Unfortunately that’s a common theme in long term marriages. At some point when the LBS feels unhappy the marriage is up for review. If she doesn’t put in any effort she’s not going to magically fall back in love with you.

You made the statement that you don’t want your W and you don’t want another woman. I would argue that if that’s the case why can’t you just keep living like you are right now? Continue to GAL, detach and work on yourself. You’re way to focused on what she’s doing and saying.
