Take note of the one who scanned over his phone.. this sort of controlling nosiness is quite common among sects where members get (imaginary) brownie points by seeking to know the personal bits of others lives.
And to add to that, JW's believe it's their duty to report any "wrong doing" they may find out about and can even be disciplined themselves if they don't....and that's not the half of it.
As someone who lost a father at 60 and father in law at 48 because they refused a blood transfusion, you need to know that JW's are prepared to die and let their spouse and children die rather than take a life saving blood transfusion. If you were to pursue a permanent relationship with your JW boyfriend and one day have children or need blood yourself, he'd be torn as to whether or not to save them/you at the expense of his and their "eternal" salvation. His family and fellow JW's would pressure him to allow them to die and he'd be disciplined if he didn't . This is not an exaggeration.
You'd either have to become a believing JW yourself, go from door to door preaching, not celebrate Holidays or Birthdays and not vote or he would be disciplined (disfellowshipped) for continuing a relationship with you. If he was disciplined or left the religion altogether, his family and friends would have nothing more to do with him.
2 Corinthians 6:13 Do not be unequally yoked with unbelievers. For what partnership can righteousness have with wickedness? Or what fellowship does light have with darkness?
Genesis 24:3 and I will have you swear by the LORD, the God of heaven and the God of earth, that you will not take a wife for my son from the daughters of the Canaanites among whom I am dwelling,
To JW's you are an "unbeliever" " and your are a "daughter of the Canaanites" because you are "of the world" and not a JW. To them, he is a danger to them because he is seeing you and he must be disciplined to protect the congregation because they have the "light" and you are in "darkness".
This hurts now, but in the long run you'll be better off that this happened.
