DB is getting married in a month, initially he didn't want anyone there as he can't afford a big do. He has since invited DH and I plus our 3 DC's & my mum & dad, who have been divorced for 17 years.
DB really doesn't want a fuss but our mum is now insisting our dad's GF of a year cannot come & feels that DB should invite his step sisters who he doesn't know very well because they live with our mother and she will be embarrassed if they aren't invited. She is also dropping hints that he should invite our uncle and aunt who we don't really know.
She also wants teh reception held at her house, our father isn't keen on this.
Both parents have been re-married (and re-divorced) since there own divorce and have met the other's partners at family events so there is no reason for my mother to be difficult about this.
Is she being unreasonable?
