Is this acceptable behaviour in a marriage. One spouse chooses as and when they respond to conversations? Apparently if they have nothing of interest to add (from their perspective) then they don't need to respond or engage in the conversation?

It depends on the conversation. We're both very talkative, but there are some subjects we don't share a mutual interest in. He's interested, and chats about the horses as pets, but has no desire to have a general horsey conversation or listen to me talk at length about riding. So it would be far more rude for me to expect him to converse than it would for him not to join in. Likewise if he wanted to talk in great detail about
complex computer programming, my eyes would start glazing over.

I'd ask him why he looks at you then looks away, saying nothing. He sounds contemptuous.

I wonder OP, if you just didn't chat for a few days (not sulk, just not do the chatting thing), he might suddenly start to engage you in conversation? Or do you think he would live in silent bliss?

Depends. For example sitting in bed, I’m trying to read but my DH decides to play a game with a running commentary that he seems to expect me to respond to. It is annoying beyond belief. I just want to read my book. I give zero fucks about what is going on in his game. I don’t want a conversation.
