people always say that you will lose the desire for each other in the new system. Personally I always had a problem with the idea that just because you die, you can't remarry. If it is natural for us to have a mate, then why can't we marry after being resurrected, and if we had one long time mate on earth before, why not that person??
but it fixes the opposite logic that if you remarry after your loved one dies when later upon resurrection and you are no longer free for your mate who has died.
