JWs require chaperones for dating. JWs don't date outside of their kind per their interpretation of Biblical mandate. JWs only date for marriage.
More important than the dating angle, I must ask if you really know what you're going into. Yes, you study with a lovely couple. That lovely couple would let their child die refusing blood transfusions, would never let that child have friends outside the JW group to any real extent. That lovely JW couple would shun their child, family, friends, or each other if one ever left that faith.
Please realize that you are unknowingly dealing with what amounts to a "high control religion", a cult. We've all been there. We've all lost families. We've all realized that much of what we were taught were lies and propaganda.
Please, for your own sake, don't get wrapped up in the cult, nor a cult member. Your life will never be the same. Do your own research with an open mind.
Oh, and welcome! :)
