It all worked out for us in the long run but I don't think I'd suggest it to many other people ;) I think it takes a lot more work and possibly luck that you will both grow into people that can actually live happily together.
The story as to why we got married so young is really simple. He left for the Army in August of 2002. We missed each other so very much so I wanted to move by him in Oklahoma. The only way that would work is if we got married. Turns out that he was deployed to Iraq 3 months later and I was back to Wisconsin for another 9 months waiting for him some more. Then back to Oklahoma I went.
Here are some pictures of our wedding. Enjoy!
