angie, you say you work together alone, no employees?
thats the way we do it. my wife an i have worked together for three years now. no employees. 100 hour weeks. yea, its tough. you just got to remember that you love each other, and steal kisses throughout the day. if you have a common goal and a common route to get there, that helps. try talking to him over a stiff drink. we usually listen better after a couple belts. what works for us, is on our day off, i walk the golf course, giving her space. remember, the things you are feeling, he probably is feeling too. just talk it out. but i think the primadonna attitude has got to stop, period!
good luck
