Balancing relationships in the afterlife
 

Have a sort of peculiar situation maybe someone has insight about. If someone has had 2 wives (or husbands) and loved them both very much here, what happens in the afterlife? Seems like earthly emotions could become complicated.
Even if the wives/ husbands don't know each other here, how would they get along in the afterlife? Or would they even know of each others existence?
