For the love of your wife ....Don't do it!
At the moment she is in a tricky enough position, with a husband not supporting her faith any more. If you d/a yourself she will have to consider everything that she says to you ,since she is not permitted to have a "spiritual conversation" with you. If you say a blessing over a meal, that will have to stop, if you raise the subject at home she is supposed to stop her ears , out of loyalty.
She has to make choices, will she choose you over the congregation? Some on here have had marital separations as a result.
I can only say from my own experience. I am technically just inactive...sometimes I attend with her - it keeps us together because that huge part of her life is not closed to me. I would love to blast them with TTAT but this way is best for both of us.
