Hi W2G...well I;ve been reading and it doesnt sound negative, the way yuor H is with you! If theres a change in the way he refers to thinks, that could be a chink in his "armour" to see what may be going on in his brain, or he could just be referring to it as "mummy and daddys" house for the simplicity for your D? But, to come back and give you a hug and a peck !? Thats a baby step surely?? And to invite you to spend time with him as a family?? Did you accept?
My sister went through this with her H, he left and she DBed and a year later they got back together. He used to come by to see her rarely and they went out a couple of times whilst apart and he told her after they had got back together that he was "testing" her to see if the changes she had made would stick. There were things wrong in their R and she, as usual, started to GAL and make changes too late...he'd already left! But he kept an eye on it, although not letting on at the time, and was looking for signs that things were different.
So...keep on the 180s !? Did you agree to more family time then?
