WIBTA for uninviting anyone who attended a winery day from my bridal shower and possibly wedding.

A Redditor (30F) is planning her wedding in a few months but has had ongoing issues with her fiancé’s sister (25F), who declined to be a bridesmaid and has been disrespectful at family events. After learning about a winery outing that excluded her, the Redditor feels hurt by the family’s apparent support of her sister-in-law.
She considers uninviting the entire family from her upcoming bridal shower, believing it will prevent further drama and that they don’t consider her part of the family. Her fiancé supports her decision, while her maid of honor warns that it could damage relationships with his family. Read the story below to see how the situation unfolds.

Here’s what Redditors had to say:
Navigating family dynamics during wedding planning can be incredibly challenging, especially with pre-existing tensions. What do you think? Share your thoughts in the comments!
My ex husband had the balls to tell me that I was stealing from the family because I was saving my allowance ( I worked as well). I asked him how spending his in cigarettes, alcohol and going out every weekend was benefiting our family.
I have a feeling ALL of his family are the ones posting here. Never have I seen so many YTAs when it is 100% clear that the entitled sister is the problem, even her brother cannot stand her.
YTA. I am surprised you are still engaged. You expect everyone to put you on a pedestal but your words tell why you don’t belong there.
I know we’re cautious to not trigger anyone these days, but by censoring so many words this website makes reading these letters much harder than it needs to be. Seriously, brat needs to be censored? Or did I get the wrong word? And liar or toxic? Or narcissistic? How fragile are the readers of this website?
