Six weeks after I married my soldier husband, I faced the prospect of a year without him as he was sent to the Far East. We knew he was going but it didn’t stop us getting married. I knew we’d be together again eventually. You come to make the best of the separations. We had nineteen years of it on and off, before DH retired. Tell her not to listen to her friends - if they love each other, they’ll make it work. It’s what you do. At least with the RAF, they tend to have longer in post than the Army, which gives families more stability. As someone has said, three hours away is do-able, perhaps not every weekend, but he’ll get a good amount of leave.
