Hi All,
Up until recently FI and I have been super lucky, not having anyone in our family trying to push us into inviting guests we weren't considering.
I am sending out our invitations shortly, and the other day my Dad asked me if I would be inviting our old neighborhood friends of our family. We shall call them Mr. L Mrs. L and Daughter of Mr. L, Daughter 2, and Daughter 3.
We used to spend almost every weekend together as families, before my parents and their parents got divorced. I still hang out with daughter 2 sometimes, but that's the only one I still see.
My Dad is asking me to invite Mr.L (who he keeps in touch with), the Mr.L's Girlfriend (who I've never met because our families stopped seeing eachother often after the divorces), and Daughter 2 and 3. It gets sticky because I still keep in touch with the Ex-Mrs. L, and Daughter of Mr.L.
My Dad doesn't see a problem with inviting only those he has kept in touch with, but I feel awkward including some, and not others. I don't have a problem with any of the people in question though.
My Dad is paying for the open bar, and so I think he gets a say in this, but my question is, is this against proper etiquette, and what would you do in this situation?
Sorry if this has confused anyone.
