WHATISTHIS- Welcome to the forum. You've had such excellent advice here - I cannot add much to it ! One reason I love all the folks on this board- so helpful to people needing advice.
The 2 major things people have mentioned that I agree with entirely is :
1. Make sure that your boyfriend is not only out of the JW cult physically ( not attending meetings ) but out of the cult mentally for good. Some here have given you great websites to check out information on that .
2. If your boyfriend was not honest with you for one year in keeping you a secret from his family- it very well may mean that he values his PARENTS opinion about his life over the importance of your and his relationship in his life. And that would set a very dangerous precedent for trying to build trust, honesty, and sincerity. He needs to grow up , or mature- like right now in a very real and fast way in order to show where his loyalty lies- towards your relationship - or towards needing approval of his former JW church or his parents. And since his parents are JW's - the whole approval thing is wrapped up with the JW & parent approval all tied in together- a package deal quite realistically.
I wish you the best my friend, but I suggest asking some really deep, probing questions to your boyfriend to see where he's at mentally, emotionally, and physically or spiritually with the JW organization. As others have correctly stated : if you don't address this now, it will be much more difficult to address it down the line . Just my 2 cents. Take care, Peace out, Mr. Flipper
