Also, your wife is mourning her mother and wants to see her again in paradise. She may not believe everything, but I'm thinking she's hoping that part is true.
I can sympathize with you Eden...if my husband started becoming a witness again I would want to die too. I don't know what I would do. It would be tempting to give him the ultimatum of the religion or me. But even if he chose me, forcing him to choose wouldn't be healthy. You must be so frustrated. I agree with other posters to be patient. Let her go through her mourning, that will get easier in a couple of years, or she may well experience some annoying pressure or hatefulness first. Meanwhile YOU loveBomb her like the new poster Tasmanian said.
its a shame she never did further research on the religion, that makes all the difference. ....maybe if she doesn't start turning back, you will make peace with it like many posters here have. One day at a time.
