Thanks for the reply, I think I’ll check that out.
But first, I’d just like to clarify. She is a faithful catholic as best she can be and this is very important to her. I should have said that sex is our biggest issue at the moment. We have discussed faith a great deal and have come to terms with the differences as best we know how, reinforcing that it can continue to work in the future. While it is by no means solved and I am aware that there will continue to be conflicts in the future, our differences in faith are less of an issue at the moment than what is directly on the doorstep right now: sex and how it operates within the Catholic faith.
While I’m not entirely sure why, though I know their significance, she is particularly concerned with sexual sins more than any other to do with us.

As for my own faith…I’d say I’m still working on that.
