I have dated all walks of TBM women TBM women are closet freaks. Don't forget too that IF you are successful in turning the lights on and deconverting her, the family would resent you the rest of their lives.
I loved him for THAT. It's gonna hurt, and it's gonna break her heart, but much less so than waiting until you've both committed to each other and start discussing your future together.
How convenient for him.
