H phones D and then takes her out to do errands for her. They arrive back and once again H doesn't come in. He hasn't been doing that of late where he used to quite frequently.
I text "You haven't called in for a while. Too busy for us these days hey? ;)"
H: "No, not at all. I didn't know if you'd want me to drop in and I didn't even know you were home."
Cas: "Of course, you're welcome to call in."
H: "ok. Good."

I tell him about the work event he helped me with last week and tell him of its success. He praises my success and throws in a teasing but positive comment related to a career dream I once had a million years ago.

It seems that when I initiate a convo he responds quite positively but he is still very reluctant to take that first step.

S is over with H again today. they are spending more time together. H is seeking both kids out more frequently these days.
