Hi 'Stillinlove' and welcome to the board.
Please take my advice, you are very young and obviously in love. Have some fun for a couple more years, by then you will have both changed and then go your seperate ways. This relationship won't last because of him being a jw and your not being one.
If you go against my advice, he will make your life a misery. And your future children's lives a misery. And his family's lives a misery. And your family's lives a misery.
I married at age 20 and knew within 2 years that I'd made a huge mistake. Don't go down that road as it took me 16 years to get out of the marriage. Do the math, that's a lot of unhappy years!! Enjoy your relationship with him whilst you feel the way you do right now, but cut and run before it gets too serious. You'll probably have tired by him then.
Good luck.
