Culturally and doctrinally, it is acceptable for a widower to be sealed to multiple women within his lifetime (he doesn’t have to choose which spouse to remain sealed to), but it is unacceptable for a widow to be sealed to multiple men within her lifetime (she has to choose which spouse to be sealed to).

I hope to be there in heaven with popcorn to witness the conversations and introspective monologues when the consequences of what they were doing are laid out. I also entertain that that aspect of mortality may not be so important to actually be worth placing my attention on those conversations.
From Wikipedia:
“Eternity is a 2025 American fantasy romantic comedy film directed by David Freyne, written by Pat Cunnane, and starring Miles Teller, Elizabeth Olsen, Callum Turner, John Early, and Da’Vine Joy Randolph.
Premise
After death, everybody gets one week to choose where to spend eternity. For Joan, Larry, and Luke, it’s really a question of who to spend it with. Joan must choose between her first love, who died in a war, or the man she built her life with.”
My wife and I will join you in the theater with popcorn! 
Plot Twist:
2 days into the week, Joan stumbles into Arthur, who insists that there is an “afterlife miracle” and Joan is supposed to spend her eternity with him. He can prove it via revelation.
