Just caught up on your sitch and came away with the similar vibe your DB coach shared. There are some strings there your ww has yet to cut ... and she tugs at them to see if you are still there. I do see the benefit by filling the love buckets in these ways... no sweat off your back as you are just being the wonderful you .. the person only a fool would leave right?
And the ... if you got a job I would not have left you crack ... total BS, I realized recently that my W is similar .. do this and I will love you .. do that I will love you ... I bascially told her like you .. THAT is not love, nor is it the love I want/need. She is using that Job thing as justification .. do not for a second buy it.
Last thing .. jumped out at me .. the time in the car and you mentioned OW must be out of town eh>? and she smiled and said yes ... Don't do that ... to me that in a way is you not only acknowledging OW and the A, but had that accepting the A vibe .... if she joins you for a ride, its a chance to show her you could care less if she went or not .. but regardless I would be PMA and that OP does not deserve a blip ... they are a fly on the windshield .. hit the wipers and give them no thought as far as the WAW is concerned ... I totally get under the surface we do think about them but do not show your hand here.
