Do military relationships move fast? They can at times, but they dont have to. Sometimes couples get engaged and then married quickly because of an upcoming deployment or duty station move. So military relationships can move as fast or as slow as youd like.

How often do military relationships last?

Most deployments last at least six months. Sure, you say, this is only half of a year. But think of the things that can occur in that half-year. You may receive a promotion and/ or an opportunity to relocate for work.
