So I need a little advice on how to handle an ongoing situation. My FI is "Catholic", I put air quotes because he is not practicing and doesn't even know what he believes as of right now and I am nondenominational Christian. This is a not problem for us for wedding purposes. My grandfather is a preacher and since I was able to know that he go preside over my wedding I have always dreamed he would. I expressed my want for this to my FI and he said whatever would make me happy etc etc. I have never hidden that I am not Catholic to his family and this shouldn't have been a surprise but when we told his family our plans his mother made this huge deal about how we needed to have a priest and it would make "the family" very upset. I stood my ground and it seemed she got over it until she came to visit and the subject came up again with the same results. I talk to the FI about it and asked him to talk to her because this wasn't a conversation I want to have every time the wedding is brought up but he never did. How should I handle this because I am certain it's going to come up again? It's non-negotiable at this point and I don't want to be rude or mean because she's going to be around for a long time.
Also a little gem about this woman - I stayed over at their house when we visited them and when I came back from taking a shower she had left a book about the Virgin Mary and another one on converting to Catholicism on my pillow....
Please help! Thanks!
