My finances cousin is not invited to our wedding?

Hello. Me and my fiancé are planning our wedding and had a dispute. I told him his cousin is not invited to our wedding. Hear me out here. His cousin has provided him with a lot of drugs such as coke heroine and meth. They sold weed together when they were 16, and would get drunk on his aunts couch from 15-20.

i believe this cousin has done nothing positive for my fiancé, and has only hurt his prospects in life.

he is a continual negative influence and my fiancé is a follower and wants to be included so will do what his cousin says.

my parents are paying for the wedding, and they said they will not pay if the cousin comes. I do not blame them and don’t want this guy anywhere near me.

how do I mitigate this or is my wedding off? My fiancé is pretty upset.
