WIBTA 3 years ago, my ex boyfriend proposed to me at my sister's wedding, in front of everyone, while giving what was meant to be a best man speech (he was friends with the groom). It was not approved by anyone, especially not me or my sister, and I said no in front of everyone, and he stormed out.
This definitely distracted from events so I left shortly after, apologising profusely. It's been a few years since then. My sister has said she's over it but she really isn't because she brings it up every time we see each other, and she's made it clear that she still holds a grudge.
We were really close before (I was her maid of honour) but after that she sort of pulled away from me.
I'm now engaged, not to the proposal guy, to another fella. We're planning the wedding for early 2022. My sister has been "joking" about "payback" for years now, saying that when I get married she's going to do something to "ruin" the wedding.
I don't know what, but I have my theories, the front runner being announcing a pregnancy or some other milestone during the reception.
We've had a conversation recently (about a month ago) where she said something like that, and I've said "I know my ex was a douche but please remember that I didn't want him to do that and please don't pull a stunt at my wedding" and her response has usually been something like "wow, yeah, I bet someone announcing a major milestone at your wedding would really ruin your event, though you probably wouldn't understand that unless it happened to you", or words to that effect.
I have apologised multiple times, but it's been 3 years and she still holds a grudge against me.
I was talking with my mum earlier, she asked if I'd started planning yet, I said no, and mum says that I should get my sister to help and I just sort of said that I'm not even sure about inviting her.
It just kind of slipped out, tbh.
In the rest of the conversation I admitted (after mum pressed me) that I was unsure about inviting her because of these "jokes" she's made over the years, because if 3, nearly 4, years later she's still making these "jokes", then they're probably not jokes any more, and inviting her might not be a good idea.
Don't get me wrong, I'm not one of those brides that expects everyone to just put their lives on hold for my wedding, but I feel like she's basically said that she is planning to fuck up my wedding.
Mum, however, thinks I'm being unfair, that my sister is allowed to have feelings about her wedding day, and about mine, because my ex's actions did affect her day, and said that my sister is most likely only joking and I shouldn't take what she's said seriously, and definitely shouldn't leave her off the guest list for my wedding because of the jokes.
She's also said that if my sister isn't invited, then she (as in mum) won't go either, in solidarity, and called me a bridezilla.
WIBTA for not inviting my sister?
