Should I stay or should I go?

I am a nurse. Born June 7,1976. I hve a 6year old boy born December 12,2010. My husband works abroad. I feel like a single mom. Thou I am still married. I work in Las Vegas. Sometimes, I ask myself if this is where I really wanna be in my life. There's a question coz hubby is not here. Thou my son is very happy. What can u see in my future? Should I stay where I am right now or should I venture other places?
