Hey, LunaFling, I am so sorry this is happening to you.
My family is really treating me bad lately too. I have been asking them questions about 1914, and other stuff that they don't like.
I am single, and I have a friend from out of the country that I set up a party for. Now my own family tells me not to go. MY OWN MOTHER. She acts as if I am 15 years old. My brother, who is disassociated, is so nice to me, even though I for years treated him bad.
So remember that they are doing this because they are brainwashed. They really think they are better than others and have a right to treat others bad.
My suggestion is the same as others here, I would go to the Kingdom Hall, be nice, wait in line to give congratulations, and as the scripture says, "pour fiery coals on her head."
The receptions are boring anyway, and she will be thinking about how you were nice to her.
Bonafide
