What Is Proper Etiquette Regarding

I say go to the wedding with your new husband.

Go to the wedding - be an adult and be gracious to the ex and his wife - it`s not like you have to sit with them or talk or dance with them - this wedding is not about you!

No matter what, you married that man and he was that child`s uncle for a while. She grew to love him as well as your brother grew to have a relationship with him as a brother-in-law. They have a right to invite him to the wedding because they love him as they love you. This wedding is not about you and it isn`t about him. You both have moved on obviously as you are both remarried. You are there for your niece. The best thing in life is to forgive, forget and move on or you will not grow if you keep harboring those feelings. You have the move on part, now you need to forgive and forget because it is obvious that your family plans to continue to include your ex in their gatherings. Be there for your family and enjoy the day and any others that may come.
