Welcome to the board!
So glad you've joined.
I have read research articles where couples in very happy long term marriages, when one spouse passes one, the surviving spouse will usually marry in a shorter amount of time.
Sounds like you had a very happy marriage. What a shame that your daughter does not wish you to find another loving spouse.
Could you sit down with a 3rd party, like your minister along with you and your daughter, for a calm discussion?
I even know of several married women, who before their deaths, 'choose' their husband's next mate as a replacement.
The wives wanted their husbands to continue their days filled
with love and happiness.
Your own golden years should be filled with joy and happiness. Wishing you all the best in your search.
