This might get long, and I do apologize.
I would recommend letting go of the religion angle. My mother was a hardcore Catholic, and back then, I was a lapsed Catholic. Whenever we would talk about religion, it would end up in screaming match. Other than that, we got along very well. So we decided to leave religion out of polite conversation. I would help her with her youth group and religious ed, and she would not force me to go to Mass.
After she died, I came back to the church. I think she was asking St. Monica up for tips!

If she had been in my face about religion, I doubt I would have come back. It might be painful now, but you have to let people come on their own terms. Didn’t St. Francis say something like “Preach the Gospel always, and when necessary, use words”? I persoanlly detest people who are in your face trying to convert you, I want to do the exact opposite.
