I am trying to understand what that 'something' is...he is a very intelligent and good looking man. He is married to an intelligent and good looking woman (not a fat, frustrated housewife – but that’s should not be a excuse too). Anyway, we both work and we have a beautiful young family...what is that the 'something'? Lust? I don't want a partner that can be THAT shallow.

Reading this, I think I know his problem. Sounds like you are intelligently trying to smother him. I agree, the guy is probably looking for some "space". doesn't mean anything by it except everybody need an escape from reality occasionally. I do about once every 3 or 4 months (as some here can attest to) my wife does it more often. She takes sanctuary in the church. Different strokes for different folks.
I can tell you this, though. If you don't learn to be a little bit flexible, you won't have to file for a divorce. You'll drive him out. Unless he doesn't come home before daybreak and he doesn't do this ever other night or every weekend, or starts leaving you alone (unless you have been putting him off already) he's just blowing off stress. You attitude screams stress at home as well from what he gets at work from my POV.
Again, this is just my POV of what I'm getting from reading your post. And yes, I've been married a long time and several times as well. I've also been in Asia nearly 30 years.
