My future wife wants me to be unsealed to my previous wife. We divorced many years ago and she has since died. We are still sealed together. I don’t know what really to tell her other than it will be sorted out when we die.
This is a difficult question and request from your soon-to-be wife: I hesitate to giving you an answer for this particular issue only because I don’t know why your fiancè is requesting this from you. One can only speculate and with topics as sensitive as this, it’s better to lean on the side of caution.
However, here is a link to a previous question similar to yours and I hope it could bring some relief and comfort.
One last link where, even though, not at all related to your question, it does however provide some insight into eternal marriages.
The one thing I do want to say is this: be open and honest with your soon-to-be wife. The worse and often most futile mistake couples make is keeping their feelings inside and not share them with each other. Also listen to her and ponder her thoughts.
A favorite quote of mine from Tony Robins is:
To effectively communicate, we must realize that we are all different in the way we perceive the world and use this understanding as a guide to our communication with others.
