Sounds just like me and my late fiance. We used to say that, except for the fact that we were opposite genders, were different ages, and knew that we had no overlapping family history (at least not in the last 3-4 generations), we could have been identical twins separated at birth.
I, too, plan to write our story someday, when I get to the point where his loss is not so excruciatingly painful. I've been talking about doing it since shortly after we met, so I need to make it happen someday....
Even though this is a relatively old thread, it was so much fun for me to read about your experience. Glad this old thread got revived.
