Re: Wife found religion
Maybe she feels she can't talk to you about it because you're not willing to listen. I mean look at it like this. She has this experience, that whether or not you believe in it, is important to her. How you respond to that will make all the difference.
One of the hard things about relationships like this is that she is going to be VERY excited about it, and the more you hear about it, the more you're going to resent it. She's probably trying to do the right thing by not bothering you and talking about it 24/7, but it's probably what she wants to do.
Look at it from her point of view, she's found something really exciting and she would love to share it with you and let you be a part of it, but she knows you aren't interested.
I'm not sure I know what the "right" thing to do is, but I know as your wife, with someone who found something important to her, it's probably important that you be at least willing to talk to her about it and show genuine interest that she has found something special. You CAN do that without proclaiming your undying love for God.
Think of it like the dad who goes to his daughter's boy band concert. He's not going to get a tattoo of Justin Bieber, he's there to show that he cares enough about her interests to get involved, even though he's not really into it.
