You do sound like you are doing the right things to at least keep the road home paved and smooth, as it were...
I find that I can do something positive and not have it recognized or sometimes I will get a "thank you"... it's rare... if I do something negative or really and persistently "poke the bear" I CAN get a negative reaction... not always, but usually... yet even if it is really "bad", my W still will not file or even threaten D... she does everything in her power to outwardly not emotionally connect with me, whether it is positive OR negative...
So yeah, even the negative stuff doesn't get much response... it's like those times when you are out and about, maybe in a bush walk, and see movement in the periphery of your vision, yet when you look directly at the spot you thought you saw movement, there is none... you begin to discount your own senses and instincts...
Have fun with the 180s... and have fun with life... just try to keep on the high road, even if you finally decide you are done... if nothing else, you will know that no matter the results of a R of the M or a D... you had a positive impact...
BTW, my W actually said to me recently, "You're a good guy, you just have some sh1T to figure out." She just can't seem to come up with any examples of the things I need to figure out... ???
