Oh wait, I didn't see this little gem before:
Two years passed. I had moved back to Oregon and it seemed like we had written a jillion letters to each other. I proposed, she accepted, and it was eventually arranged for her to come up. The first time was for a week, and it seemed like the world was empty after she went back. Finally we decided not to wait any more, so she came up again and we were married. We were both young, scared, but very much in love.
So you were 18 and she was 13 when this all started.....sounds perfectly healthy to me.
