DH often gets emotional saying how proud he is of our DC but I sonetimes find it quite jarring that he'll say that , and yet, not listen when they tell him things, walk away mid sentence, not entertain the idea of going to their choice of restaurant, tell them he's coming to an event but then prioritise work or miss an award ceremony because it clashed with his hobby....
Words say one thing when often actions suggest something different. (I'm not sure how DC interpret this, I've never asked them)
Committing to too many things at the same time is an ADHD trait of DH....but when pointed out that there's a clash, family stuff comes out bottom 95% of the time - including his own family - siblings, parents etc. Thinking ahead is also a big stumbling block and I just don't think that considering how someone might feel if you promised something and then don't go through with it (^and don't tell them) comes into his mind.
I'm sure he does love us but I think we mostly have to hear it, and believe it, not necessarily feel it IYSWIM.
