It doesn't sound minor to me what you are describing. You captured a number of different pieces that highlight H. owning his own part of the equation. Okay, maybe not fully, but he's showing active signs of participating. The part of him living in the house probably does feel foreign and I think that's normal enough, but it's perhaps a little soon for that. The fact that he's continuing to be engaged in C. and maybe inviting you for some time away is a big plus. AND, you have a good experience when you are together, that's a big reinforcer that there is still important connection and chemistry at some level happening.
