You did the right thing, definitely. Shes a ***** and deserves to be told off. Write a letter to your brother, explaining how you refuse to allow your mother to be treated that way, and if he doesn't like it, thats his problem.
First, a male is a fiancé and a female is a fiancée. I have to reread what you wrote because it's confusing. You wrote (and I'm commenting in parentheses): "So apparently she (your mother) didn't get an invitation to the bridal shower, because it got "lost in the mail" whenever (you mean 'when') her sister (Your mother's sister - your aunt?) and her cousin (Yoyr mother's cousin?) got one.
Her sister (You last spoke if your mother, but I think you mean your brother's fiancée's sister) lives two houses down from us... Yeah. The soon to be wive's (wife's) sister was the 'organizer', we'll call her B was behind all of this. B also snubs her (Her?
Who? Your mother? I thought she didn't go to the shower?) at the bridal shower and wouldn't speak to her (she - her, very confusing)."
What would I do if my mother didn't get invited to my brother's fiancèe's bridal showe because it got "lost in the mail". So what was the problem? Your mother showed up, but was told she wasn't invited?
Or she was told the invitation was lost in the mail. I don't understand what happened that mafe your mother come home crying. And if coyrse you SHOULD NOT HAVE sent any FB rant.
It's not your place. Your mother is a big girl. She can talk to her son (your brother) and ask what happened.
And even YOU could have asked yoyr brother what happened. It's rather apparent that your brother is giving up his own family, and favoring his soon-to-be wife's psycho family. This is not a new concept.
You need to discuss this with your mother and LISTEN to what she says. And then flow what SHE thinks. And maybe you'll end up not talking to your brother ir his "in-laws" any more.
But listen to your mother. Don't do anything else on your own. This is your brother and his fiancées show, not yours.
Yes, you went overboard. And you got yourself involved in the vicious things that women do to each other.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
