I don't want to bore you all with any long story... I simply need help. I'm too emotionally attached to this lady and she has opted out. How can I detach myself complete from her??

Simple. Detach yourself from her.

By buying sense, even if it is second hand sense

Brother any Banny that says she want to leave, let her go. Find another one.
In Chris Brown song Lost and Found "if you loose one you get two" unless you are afraid to woo girls. No time to check time.
Even if na few hours to your wedding your woman change her mind let her go, ask those in troubled marriage them go explain better.
If you are feeling down you can join me let finish this tea together or you meet the boogeman for some joint make una bla the weed make your eye see something Spiritually.
life is short man.
