No, real friends may not understand, and they may not support it (they cannot as Catholics), but they will remain loving toward Carole (if only for that cute-as-a-button "e" at the end of her name ) Supporting and understanding should not be required or even expected.
Thank you for the compliment on the "e" - though in the interest of full disclosure I will say that it has long been an annoyance to me. Now I have a new appreciation for it.
And you are right. I do not expect support in the "Yay for you! I'm so happy for you." meaning of support. And I don't expect people to understand. I mean I get it. They are Catholic (and for the most part serious, devoted Catholics and not the "Catholic in Name Only" types). As Catholics they hold certain beliefs about the Catholic Church that should make it difficult, if not impossible, to encourage me on this path.
However, I do expect that my friends (those people who care for me in a more personal and less generic manner) to respect me and support me in the "I don't think you're doing the right thing and I am very concerned for you. But I am not going to be rude, mean or dismissive of your thoughts and concerns."
To date I have received far more of the respectful support from friends. In fact the response has been better than when I told Protestant friends I was joining the Catholic Church when I actually had people shun me because I was "apostate" and "going to hell" for "leaving Christianity." And for that I am eternally grateful.
