I know general etiquette says "do not talk about wedding-related stuff to people who are not invited."
BUT
I have an acquaintance, who was not invited to my wedding (we really don't talk much, usually), however this acquaintance just got engaged about a month ago. A lot of our mutual friends said she should talk to me about wedding planning since I'm so close (and have done a TON of research in the area).
All of a sudden, this aquaintance and I are talking quite a bit - and always about wedding planning.
I feel weird talking to her, since she's not invited to my wedding (and it's too late to invite her), but I think it would actually be rude NOT to talk to her....
