A few years ago, I left a phd program with my masters for personal reasons, as well as being fed up with a professor who ignored me and a bit burnt out on the non-stop teaching/studying/research going nowhere. I do not regret for one second that I quit, because I know neither my long -distance marrage nor my sanity would have survived it. I now have a good job as a military contract scientist, and my boss feels that I could earn my PhD with some of the research we are doing (not secret) if we could find a university willing to take on a non-traditional student. I don't know how to broach the subject of my leaving grad school though. Should I put it in my SOP? And if I do, how do I phrase it so I don't sound like a whiny quitter? If I don't, they are sure to ask during the interview. How do I answer them? I appreciate any advice anyone might have.
