Would he be willing to look at some books you have? Such as Crisis of Conscience by Ray Franz, Captives of a Concept by Don Cammeron, The Four Presidents of the Watchtower by Gruss, just to name a few. If he won't why not? Is he asking you to do something he himself is not willing to do? Is this really the kind of relationship you want?
Can you bring up topics of scandal about the wt such as the UN, blood issues, pedophile problem, Malawi/Mexico, transplant flip flops, rape flip flops, etc.... with him or his family?
Every new ubm (unbelieving mate) thinks 'their love' is stronger than the wt, can overcome any problems arising from one being a cult member, we on all the ex jw boards have heard it over and over and over. I thought the same thing. Your 'love' will be abandoning you five times a week and on Saturdays to do field service. Then if he is very lucky he will get bible study of his very own, there goes yet another night away. His first love will not be you and any children, it will be the organization and the congregation as it must be in the jw's. You and your relationship are not special beyond what every other broken hearted ubm has thought and gone through. Learn from other peoples mistakes in this instance, your future life and happiness depend on it and that of any children you may have. I wish you well.
