I cant stand my fiancee's friend's wife?

We are 40. My fiancee is friends with "Jack" and he is nice. He recently married a trampy woman "Jill" who I find very irritating and self-serving. I opt out of spending time with them as a couple. My fiancee visits them without me and thats fine with both of us. The issue is our wedding. I cant invite the friend and not his wife. I really cant stand "Jill" and dont want her near me. I dont want her at our wedding. My fiancee is fine with us not inviting them to the wedding because he knows I dont like her. Can anyone think of any creative compromise? I would actually have this guy IN our wedding if it werent for his wife because he has been my fiancee's friend a long time. I dont often dislike someone this much but she is one of those rare types. I dont want my fiancee to look back and regret not inviting him but I dont want to look back and regret having her at my party and pissing me off. Im not fake and not the type to just paint on a smile. My fiancee is staying neutral. Your suggestions are warmly welcome.
