<human>: Can you condense the text into three sentences or less?

A little background before I begin: I met this group of people (and my fiance) through my ex-boyfriend who had known them since high school. I was friendly and cool with these people, but never really hung out with them outside of shows (my ex-boyfriend and fiance we in bands together and also with this group of people) and social group gatherings. After my ex and I broke up (which he told them that I had cheated but it had actually been him that cheated on me our entire relationship), they ghosted me and essentially chose him over me. 

After they ghosted me, I deleted them out of my life, although my fiance is still friends with them and even in a band with a few of them. I've told him how I feel and that I'm fine with him hanging out with them but that I would rather not and to not bring them over to our house when I'm there as I feel it would awkward for me. He said okay and has not put me in situations that would make me uncomfortable.

But now here comes the awkward part. We are getting married in a few months, and we have to decide the guest list. I do not want these people at my wedding because it is supposed to be the happiest day of my life and I do not like these people. But they are my fiance's friends and I feel like he would want to invite them and that they would be offended if he doesn't (also a few of them have/had invited him to their weddings but did not mention me specifically only saying he could bring a plus one even though all of them know me and know that we are together).

So my question is: how do I tell my fiance that I don't want a certain group of his friends at our wedding?
<bot>: Getting married soon. A group of people ghosted me but are still friends with my fiance. I don't want them at our wedding but I don't know how to tell my fiance.
