My wife wants a divorce if I dont get out of the army.?

I am a medic in the military, have been for 6 years. I have been married for 7 years. We have two children. I have until March of 2013. She says that she will divorce me if I dont get out of the army. I dont want a divorce but how can I get out of active duty, without getting an OTH or dishonorable?
