What happens when "Life Mate" dies??

[Taronu 'ewan]

Here is an interesting dilemma, what happens when your "Life Mate" dies??
Considering the time it takes for a Na'vi to find a suitable mate (sometimes months and even years). Once tsaheylu has been established and mating taken place before Eywa, the couple are now life mates and are forever more!!
Then through accident, natural occurrences, or murder, a life mate disappears!
What happens to the remaining mate / partner?? Although contact with the departed is still possible through the "Tree of Souls" or the "Tree of Voices", it is not possible to physically touch or feel the lost loved one!! This would have to be one of the most cruelest and painful feelings to have to undergo for any Na'vi, to have found and loved the "One" only to never be able to hold, caress, and make love to ever again!! Does Eywa allow the living mate to move onto a new mate?? Or do you have to suffer in silence until your day to go Eywa arrives?? The Na'vi love is from what I understand, so powerful it ties the two together for evermore, and they will go on within Eywa when they both leave the physical domain, but it appears to be a hurtful feeling when you lose your mate (as we feel here on earth).
