This will sound mean but bear with me, when you leave for extended periods of time DO NOT acknowledge that you are leaving. Distract the dog and then slip out quietly. Do not make leaving a big deal. Likewise, do not make arriving a big deal. Once you get home, ignore him for 5 minutes or whatever while you settle in. Praise calm, collected behavior and ignore bad behavior.
I have 3 roommates and 4 dogs one of which is mine. When I get home all 4 of them are calm and barely make a peep as their tails wag in happiness. When everyone else gets home they are barking, crying and flipping their fucking lids because my roommates make it a huge deal. Most dogs are fine alone at home as they'll just sleep a whole bunch. If you want to leave the radio/tv on or something it might give the illusion of company. You can also try looking into what's called a Thunder Jacket which wraps around the dog and simulates cuddling/comfort. Probably shouldn't leave that sucker on for more than 3 hours as it could cause a rash or something.
as far as not sleeping with you, do you mean not on the bed or not in the same room completely?
