Honestly, the only thing I could say is simply what has already been kindly expressed already here.
I do hope you will understand what you are truly up against.
It's wonderful that YOU have such an intense and unmitigated love for this woman.
But Jehovah's Witnesses are a nightmare to deal with, no matter how true and dedicated your real and true love is.
Jehovah will win out, but it's more or less the society's doctrines and edicts that have robbed her of any sense to see what you are offering: is a lifetime better !!
I hope you'll heed some of the kindnesses that have been availed to you, from people who know only too well what goes on inside that organization. We may not know you personally, but we DO know what you are up against. We do not wish any kind and loving human being that empty and torturous futile journey.
Please keep us posted will you.
You deserve someone who will love you for who you truly are, and not second class to jehovah.
My kindest regards.
