Honestly Dom, she's under a great deal of stress. She has a "C" level position at a mid-sized software company. She oversees all the non-US divisions. She's got people all around the world and I was one of those people for nearly 6 years. (I was a upper-mid mgr and in my last role she was my boss' boss.) Job/Career stress has played a HUGE role in creating our situation, both her's and mine. Now that I'm unemployed it's playing the major stress in my life and it is with her too. For her she feels stress and responsibility because she asked me to leave my job and strike out on my own career. Trust me working together although nice often, was a huge stress on our relationship. I highly advise against working with your spouse!
