Your husband reminds me a bit of mine, shootingstar. My husband generally doesn't talk much, so he tends to not mention things a lot. One time I got annoyed because he bought a new cell phone and contract without discussing it. When I got annoyed he pointed out that he had mentioned it. About a week before buying it he had said "I'm thinking about getting a new phone." and I had said "Oh" and promptly forgot about it. Turned out that his idea of talking about it meant mentioning it and my idea of talking about it meant discussing it. I just talk more than he does though, so that makes sense.

If your husband was sure that you wouldn't mind him doing these things he probably didn't see any reason to ask you about them in advance. He just mentioned them when they came up in conversation.
