One of my friends (and his mom) will be the officiants for our wedding. Do we also invite his wife? I know couples are supposed to both be invited but he is only invited because he is being the officiant (plus I hardly know his wife). I think it would be weird if other vendors brought their SO so I'm not sure what to do with him since he is only acting as a vendor for us (who we happen to know). We are having a small wedding (80 max) so I'm not sure what to do. If we were having a larger wedding she'd be invited too but we aren't. So do I invite her because she is married to our officiant or not?
