Must I file for Divorce in NC or another State?

My husband from whom I was about to serve seperation papers (under NC law, to preceed divorce) is in the military, and is a resident of another State (in which we were married) and I am a resident of a different state, in which we last lived, before moving to North Carolina about one year ago. We live here “on deployment.”

QUESTION: In which State may I/must I file for Divorce and/or Seperation? If given the choice, I’d prefer to file elsewhere as it seems that NC is more difficult to navigate than other States in terms of seperation and divorce.

Thank you,
Smacky
