Am I The Asshole? In Laws Edition

Am I the asshole for telling my brother how I honestly feel about his marriage slash decision to marry his now wife? She posted some very skanky videos of herself at their joint bachelorette party in Vegas, and I immediately saw even more red flags. Her behavior was super embarrassing. Not only because that's not how women who are serious about marriage act. Can you tell how I feel about this one already?

Oh boy.

But because the extended family, who I hold in very high regard, saw what she posted. Anyways, they got married and I kind of stopped talking to him slash them unless required. I just had nothing nice to say, to be honest. My brother brought it up one night when he came over to talk and I laid all my cards out and broke down and cried and said I was disappointed and hurt, but that it was a me issue. Now shit is not the same and I'm grieving. What was? We were very close and now we feel like distant relatives. My mom told me that her parents know I don't like her and kind of hate me now. I didn't go looking to make enemies of people I might end up having to see at a Christmas party. But I did tell my mom if they ever want to have a sit down, I will gladly have one since I have the receipts of it all and will happily back up everything I've said.

Oh, wait. What? Wait, wait. You want to sit down with your sister in law's parents to show them how much of a skank she is?

Yeah.

Oh, so you want to turn her parents against her too? Wow. Okay.

All right, what's your, what's your gut check here? Who's the.
