I believe it totally depends on the people involved in the relationship and where they are with their lives. I also believe where the military member is at in their career can have a roll in it as well.
As for personal experience, my husband is currently in the Army National Guard. He was in the reserves for the first 6 months or so of our relationship, then went to active duty. He was active duty for the rest of the time we were dating and the first 3 years of our marriage. We spent the second year of our marriage mostly apart because he was deployed overseas. He is now Army National Guard (has been for a little over 6 months now).
We were both older (me late 20s, him early 30s). I had been in the Army National Guard when I was younger, so I had a good bit of knowledge about the military and the military lifestyle. I knew the moment he went to active duty while we were dating that if things went well between us, I’d be moving. I have a career that is very portable, so that has never been an issue for me.
Communication is a huge thing in relationships when one spouse is away for any length of time (military or otherwise). Both people in the relationship have to understand that and come to a compromise about how much communication is needed for them to feel connected (this varies a lot from one person to the next).
As for all the moving, I love it! We’ve seen and done things we probably never would have done if we weren’t stationed in those areas. While we were stationed in Texas, we went to San Antonio and saw the Alamo and the Riverwalk. We also went to the Sea World down there. I don’t think we would’ve ever made a trip to San Antonio if we weren’t already in the area. When we were stationed in Kansas, we went to the Wizard of Oz museum. Another thing we probably never would have done if we weren’t already in the area.
Being away from friends and family can be hard sometimes, but meeting new people and making new friends has been fun for me. I keep in touch with people all across the country (and even other countries) now because of friendships I’ve made over the years. The friends I made in Texas and Kansas have now moved to other areas as well, so now when I go visit them, I’ll be getting to go to more new places!
Separation from my husband stinks, but we make the best of it. While he was deployed overseas, we talked when we could on the phone or on the computer. I sent care packages and cards every week. He sent a few letters in the mail to me as well. There were times when I didn’t hear from him for a week or so. Those times were very hard (and very scary), but getting that call from him to say he’s okay and that he loved me made it all okay again.
One of the best parts of all the separations is all the reunions! We have had so many first kisses, it’s amazing! We’ve had our first ever kiss, our first kiss in various states, first kiss goodbye, first kiss during R&R, first kiss after a year long deployment… I could go on and on. If the people in the relationship can look at those types of things and enjoy their time together, I think it provides a better overall outlook for their relationship.
