Who would you want to spend the rest of your entire life with?

I'm just fine without mystery in my relationship. However, I sincerely hope that my partner does not die for many, many years after I do.
On the other hand, last time around, I died in the war and her life continued another 40 odd years, which explains the huge age gap between us now. So, if she did die soon after me, it would be a kind of "reset" and next time we'd be nearly the same age again. That would be cool.
