I have seen a lot of soldier's who have good healthy marriages. It does take more work, but it can be done. I don't really feel like I can give any advice because I'm not sure I can say my marriage is the most healthy. I do believe that both people in the marriage have to really want it to happen because in the military it is too easy to get out of. Some spouses disappear while their soldier is deployed. Some soldier's just stop communicating essentially disappearing themselves.
I think you really as a family have to prepare for deployment, not just the person being deployed. You have to have a plan and a goal. Right now divorce in military is at about 80%....I'm hoping not to fall in that stat, but will see I guess.

When I vowed for better or worse - I meant it!
