He sounds like he is well-regarded and in demand. That is admirable, but I can see how it will have to be a conscious choice for him to decide to make more time for you. All of that demand for his attention likely feeds his ego. Just curious: How much do you feed his ego? I would imagine that you are feeling hurt and that it is hard to do if you're feeling neglected.
As you progress through your journey (reading, posting, self-reflection, revelations) you'll find a new strength in your approach with him. You might discover, like I did, that you will find compassion for your husband (something that I could never find before because I was blind with anger, resentment, and hurt). Compassion for him, understanding, learning from MWD, Schnarch, possibly Glover, peers on this board, and some sign from him that he is willing to work WITH you will give you a whole new perspective.
I agree with DQ. Don't get hung up on what the 'thing' is. Find something great and GO the weekend prior. Be prepared to give him some time to handle work stuff -- he probably won't be able to shut it off much during the weekend.
