What does it imply? That getting married to this guy is the worst idea in the world. It sounds like he's wavering a bit, but crossed fingers isn't going to help you if he decides to remain a dub.
Think ahead to future children. Being raised as a dub child is a ghastly experience, one I and many others here have experienced. And if your child should ever need a blood transfusion to survive, and your husband says no, what does that imply?
Read marriedtoajw's thread, which was just posted a short time ago, and see how horrible things can get.
Uncross your fingers and learn about the cult you plan on associating yourself with. If you have even a lick of common sense, you'll run far and you'll run fast.
