Dear Queenie,
My parents were both married before and both of them have children from their previous marriages. My mother’s ex-husband had custody of their daughter so I never got to know her very well, but I grew up with my father’s children from his previous marriage and we all are very close.
Now I’m getting married and it’s going to be a very small wedding, just immediate family, including my father’s other children, and a few very close friends. I don’t really want to invite my mother’s other daughter, but I don’t want to upset my mother by leaving her out.
Queenie, what do you say?—Can’t decide
Dear Can’t decide,
Let your mother decide. As the two of you are not close, your half-sister may not choose to attend, and if she does attend it will be only one more person.
