How will the military affect my wife?

I just finished college, got married the whole shabang. Anyways, I was considering joining the military as an officer as my next move. But my main concern is how it will affect my new marriage. Obviously there will be time spent apart, but how much? Do the different branches vary from each other? Like Navy vs Army. Is one more family oriented than the other? Are there aspects of this lifestyle that aren’t obvious that would affect me and my wife? Any insight is appreciated thanks!
