Can't let her life dictate yours bro. If you want to serve your country that is your calling. She would be a real rotten bitch to keep you from that just because she has a beef with the military. I've seen too many young men and women pass up things like scholarships, military service, and pro sports invitationals just because they were in a relationship that was doomed from the beginning anyway. You go and make sure to tell her it's the right decision.
