Um @Adam Strange
if God is important to her and it’s not inherently important to you (which you cannot change) and she is miffed by it, that might be bit of a problem perhaps. I don’t have any practical advice on something like this as much as some differences that seem like not that big of a deal, can end up emerging as a bigger deal later on

Esp being Fi lead if she values something she may take it pretty personally at times

..but anyways, yeah
