@MarkintheDark of course Spot knows that something is up your emotions and behavior has changed and he knows you better than anyone. He knows without a doubt that something is wrong with his people and he doesn't know how to fix it. I know that he wants to after all he adopted you for life.
Anyone who thinks that animals can't read and understand emotions and body language does not have good grip on the world around them. Rabbits that lose their bonded partners will get depressed and die themselves when they lose a partner (be it another rabbit, human or other being). A Canada Goose will look for a lost partner for up to 10 years before moving on if ever.
When my father was in palliative care I had 2 dogs with me Gypsy and Scout they would both head in to rooms that were wrong, that they had passed by before on the way to my father's room. Every time they did this they were needed by someone within. For a lick or a pat or a cuddle. One evening Gypsy refused to head down the hall to the room she was going down the other hall se kept pulling until she got around the corner in that hall and went to the lady sitting on the floor outside a room crying. She pushed her head in to her lap and gave her face a kiss, and then just sat there and let the woman hold her and cry. The women's father had just passed minutes before and Gypsy was not going to let her cry alone.
My point to all of this is that because you are hurting Spot is too, he may not know your intentions but he knows that something is wrong and he is trying to make it better in his own way.
