Asking just out of idle interest, following a discussion with an old friend at the NYE party.
She's in a loving and committed relationship with her partner for around five or six years now, they have a young child, live together in a jointly owned property, run a business together. They are not officially married, and (I just guess, from knowing her and her views on the topic) have no intention to marry.
However, she was not invited to her DP's mother's wedding ceremony because she is not officially a "wife" or a "fiancée". She is a bit
as she always thought that they are getting along well, and now it somehow feels she's not good enough (even though she's not into weddings herself). MIL insists it is just a balancing exercise of "drawing a line somewhere", and that they will be happy to see her at the evening reception.
I heard of the "no ring, no bring" rule, but I have never thought it applied to firmly established couples. In your opinion - ok or not ok?
