You might inform Brother Shithead that there are stalking laws in affect in most all of the states now and if he doesn't cease and desist immediately with his so-called watching of you, you will file charges against him and the entire congregation, whoever may be watching you. Better yet, send him a certified letter written on letter head stationary. Make up a ficticious lawfirm, something like the lawfirm of Colt, Remington, Smith & Wesson.
This jerk has no right or call to tell you what you can or cannot do. The only thing he could do is to prevent your baptism into the holy witchtower. That might not be such a bad thing anyway.
Also, I would tell that other "brother," the one you are thinking of marrying, to go straight to hell! What sort of husband is it that will report to these nazis everything you tell him? Although I doubt he would report you for giving him a blow job. You don't need hypocrites like that in your life.
If you are worried missing Mr. Wonderful, look upon it like missing a bus. You needn't worry, another will be along shortly. Maybe one that put his love for you above that of a manmade organization!
If God's Spirit is filling a Kingdom Hall, how is it that Satan can manuever the ones within that Kingdom Hall at the same time?
