My sister is divorced and my daughter wants to invite her ex and his girlfriend to her wedding. My sister is upset about this because he cheated on her with this woman.
Ex invitations

Thank you for your question.
This is a tough situation to say the least. It is never easy to combine families that have been through a divorce for the reason you have mentioned, especially for such a wonderful occasion.
My first thought is does your daughter know the details of the divorce? If she does not understand the why's she may not see the problem of inviting the ex-brother-in-law.
If your daughter still would like him to be there, you could be sure that the seating arrangements are such that he and your sister are as far apart as possible.
You also could invite the ex-brother-in-law only. Simply address the invitation to him alone. If he asks about a guest, you could explain the reasoning to him.
Weddings are a time to celebrate a wonderful couple starting their journey together. At times it is difficult to put feelings aside, however doing it for the bride and groom could help.
Best wishes!
