My T and I talk about religion. I know she is a different religion than me, but she still has a good working knowledge of my religion so we are able to speak about it. I don't view her talking about her religion as swaying me. When she talks about something I don't believe in, I just let it go in one ear and out the other and shift the topic of conversation back to something I do believe in. I can see the concern though that your husband would be swayed. I think it probably would have been better for the T to not disclose her personal status and just talk about what that meant for your husband.
