Hi and welcome!! First, let me say that my situation is almost identical to yours except that my husband has been an elder for about 15 years or so, and I only have one child. Other than that--just about the same. My discovery of the dishonest use of secular quotes to support creation was the tipping point for me and, like yourself, once I started researching, the whole house of cards came tumbling down. If you haven't read Crisis of Conscience, do it now. It's eye-opening and truly inspiring.
I haven't read Hassan's book but its at the top of my list, so I can't help you out there. I do know that my husband and I have been through some rough times b/c of what I've learned. However, he's run interference b/w me and the other elders so that my fade has been pretty easy and quiet, so that says something. He's admitted that the literal flood is an impossibility, so that's another chink in the wall. I go to Sunday meetings to keep the peace and that's it. We've reached detente and I've decided to back off. For now anyway. Once I read Hassan's book, I may try another tactic.
Regardless of what method anyone chooses, it does take time and patience. I suggest that, if you love your husband and want to stay together, go out of your way to be a really great wife and friend in every other "normal" area of life. It's sort of like what the WT advises when a sister has an opposing mate, ironically! Draw closer to him every way you can; not only will it strengthen your marriage and maybe even safeguard it, it could go a long way to softening his reception of your [frightening and threatening] new ideas.
Please keep us posted--we're interested to know how it goes.
