Help wedding officiant crisis

Tatianna

So I made a deal with my soon to be husband that as long as we get married outside he can pick who marries us. Should turn out all fine and well. But every time I bring up doing a pagan thing for my wedding ceremony to my Christian father in law. He is like I won't do that but I do this. And what he suggests is a totally Christian cermony which is not what me or my s/o want. I am asking on how I should go about telling him or asking him do what we want and actually having a ceremony both of us are happy with.
