Deb I think anything your H does that is his 'old norm' is a good sign. I'm sure that in the height of his alieness he probably acted like he was a visiting hired hand and took NO liberities of familiarity on the occassions that he came to your place.
I know that when my H FIRST started coming around here, when he was still a despicable stranger he acted as if he'd never lived here. The discomfort he felt here was palatable. BUT as he started 'breaking down' he began acting and looking 'more at home.'
It sounds to me that your H is beginning to act, 'more at home' around you and your place.....and that's ALL GOOD. T2
