Ladybird....I don't know the reasons for your daughter's "position".....but, as a mother, myself....I can relate to how deeply it must have hurt not to be i nvited to your daughter's wedding. It does sound like she is bitter and trying to be hurtful......
These things cut deep into a mother's heart....
I can "hear" in your posting that you love her....
That is what we mothers do...isn't it....we love them....even when they are unlovable.....
There are times that we just have to turn it over to the Universe...
With much empathy.....
