I once had a therapist tell me that my happiness is my responsibility. For instance, she suggested I go check into a hotel, then call my wife and invite her over, saying "tonight I'm going to f*** somebody, and I'd prefer it was you".
That seems a bit extreme, but the idea is that I do much more than just complain about my emotional needs not being met. Sexy and complaining don't go together. But sexy and confidence do!

Another thing to consider: job pressure aside, there may be other issues in your relationship (specifically him feeling rejected by you at some point in the past and not wanting to be vulnerable again). If that is the case, you may want to consider Joe Beam's LovePath 911 course. Joe does a great job at helping couples (a) get in touch with each other's emotional needs, and (2) learning to communicate safely.
Joe also has two books I recommend: his new book "The Love Path", and "Becoming One". I suspect you could find both off his website at
www.joebeam.com.
I've found it helpful to read these forums.
Good luck!
