I have been married for five years with a nine year old from a previous relationship. Ex sees his daughter two or three times a year.
She lives entirely with us.
Husband and his cousin are like brothers and husband was asked to be his best man at the end of the summer.
Cousin and his partner have often been guests and know my daughter very well.
Invitation arrived with just our names on which upset me but that’s their choice but husband collected his daughter who is 10 and turns out she is a bridesmaid and other children are invited.
I think he needs to ask cousin to include my daughter.
