Telmark - Welcome. I am sorry your find yourself here. I am just getting caught up on your sitch.
It sounds to me like you are doing a good job on the GAL.
Remember to focus on things YOU can control. Unfortunately you cannot control your W's relationship with the OM.
There's a saying around here in regards I'll pass on if you haven't seen it already - "believe none of what they say and 50% of what they do" or something similar. I would say that's somewhat true, although my DB coach has enlightened me to different interpretations of what my W says. For example, 'I don't want to give you false hope' can be intrepreted at face value or it could be something she is saying to herself.
I think at this point, initiating conversations about the M should avoided. Work on detaching more and GAL.
