Oh wow...That is so appalling.
In addition to already offered wise advice, I can just say "The only power they have over you is that which you allow"
So do not be drawn into the stupid games the Elders try and play. If you and your boyfriend are comfortable with your relationship, then there is no need to allow anyone else to pry into it!
Be happy, confident and keep your dignity.
And as others have said, don't try and wake him up by dumping huge facts on him. Just slowly ask questions about things and let him be the "spiritual man" and research things...then slowly show him the things you have found....
But I will also say one thing : Are you prepared to envision your life without him IF he doesn't wake up? You have your whole life ahead of you - don't get tied into the organization and have to live a lie....it will kill you.
