My fiances brother has two children with a girl we'll call CiCi.
She did some horrible things to my (future) B.I.L., making me detest the very sight of her. They split up over 2 years ago and BIL is with a great woman "D" who will be my Maid of Honor.
I have met CiCi once, so we're not friends or aquaintances in any way.
Here's my issue. BIL's two children will be IN the wedding party. His daughter will be my flower girl, and his son will be one of two ring bearers.
When running down my list of invitees to my MIL, she added CiCi to the verbal list of guests. I said I really didn't want her there, but MIL said nothing and it went undiscussed.
MIL is not paying for anything, but obviously she thinks CiCi should be invited.
(P.S. family is only polite by policy because she's never taken BIL to court for support. NO ONE in the family can stand her.)
Not only do I not want her there, but I'm worried it might be awkward for D.
My question is: wtf do I do?
Not invite her? Invite her and pay my photographers more $$ to make sure she's in as few photos as possible?
