Our invites will be going out in a few weeks and we are only giving "& guest" to those with significant others. A couple of the guys in our WP are each casually seeing someone and I'm not sure how to approach that situation, especially since they are our "VIPs", in a sense. One groomsman in particular is currently back to fooling around with an ex of his who he had previously caught cheating on him. I knew her from before he had met her and realized she was conniving and two-faced even then. Now that my fiance has seen how she treated his friend, he can't stand her either. Being in her presence makes us both uncomfortable.
I think this GM gets that we're not big fans of hers, but I'm afraid that wouldn't stop him from bringing her if we gave him "and guest". I don't want to cause a rift between my fiance and one of his best friends, but it is our wedding day and we should be surrounded with people we love and who love us just as much in return. Any advice on how to approach this?
(On a side note, we are also inviting another one of his exes, who he had kind of a dramatic love triangle with also involving this girl he is now fooling around with. He is on good terms with both of them, but the girls aren't with each other. )
