We went on a cruise with my fiance's family (dad and stepmom with siblings) for Christmas, where we also got engaged. We had major problems with his step sister. She pretty much ruined the entire week for us, complaining (and getting into fights about) how nobody acknowledged her "engagement" like they did with ours and how everyone likes us more. The whole cruise ended in a blow out, with her calling us fat slobs and scumbags. Her "fiance (they put they were engaged on Facebook but never actually were)" was pounding on our door threatening us. It was a huge mess. She never apologized, and we just completely cut her out of our lives since we got back. My fiance has told his parents numerous times that she isn't invited, and his stepmom insists on bringing their daughter (fiance's niece) with them, which is fine. I could tell they are not happy with his decision, however. When I have mentioned it to other people, they said that it is rude of us not to invite her. My fiance also never got along with his mom, which he also does not want to invite. She has treated him badly growing up, which I can understand. She also got mad she did not know of our engagement before he proposed. I want to leave these decisions up to him, but I am regretful for not including these people and don't want to cause drama with my new family before we even become family. Opinions?
Re: Excluding immediate family
It sounds like this stepsister is both 1 and 2.
Since your wedding is still so far away when the topic comes up of who you are inviting or aren't inviting, I would just your future in laws that right now his sister isn't invited but you never know what could happen over time and if they are able to work out their difference between now and when the invites go out, it would be great and you would love to invite her. And as for his mom, I agree with letting hit be his choice, see how things are between then also as it gets closer. All you can do is ask him before sending out invites "Are you sure you don't want to invite your mom? This is a major life event and I don't want you to have any regrets." If he still says no, then just drop it and support his decision.
2. Give this some time. Things change. Do not make any final decisions until it is time to send out the invitations.
3. Your FSIL and her FI won't disappear after your wedding. They will be connected by family. Be careful about cutting off relations unless you both agree, and have good reason. Consequences can be huge.
4. It wouldn't be the end of the world for you to extend an invitation to your wedding. It makes you look like the better person. In SOME families, past bad behavior is ignored. (Denial.) Does your FI's family function like this? If they do, it will be hard to deal with it.
The reason for not inviting someone may have nothing to do with your relationship with them. If I exclude someone I don't feel particularly close to, like a co-worker or a distant relative whom I seldom see, from my wedding, does that mean that I have to "let the relationship go" ?
Sorry, but I don't think one has to consider future relationships with everyone one chooses not to invite to one's wedding. And if they choose to interpret it as a "slap in the face," or take it personally, well, they're the ones with the entitled, immature attitudes. The only three people entitled to be at my wedding are me, my FI, and the officiant. No one else is "entitled" to be there.
But we don't know that the stepsister's behavior happened only on that one cruise. The OP didn't say, but it might have been going on all along. And even if it happened only that one time, it's still a red flag that needs to be addressed before she is invited to join the family again. It needs to be made clear to her that behavior like that won't be tolerated ever again, and will result in her not being invited to future family events.
Yes, the FI is the one who needs to make that clear to her as far as the wedding goes, but it should not just be shrugged off and the OP blamed for "not one sided behavior here" because you don't know what the OP's behavior was like on that cruise. And threats of violence do constitute an exception to any rule of etiquette about inviting people who make them. Safety trumps etiquette.
The bolded is a bullshit stretch that in no way applies to what I said. Where the fuck did you pull that out of?
I agree with your last paragraph, but if the sister and her FI refuse to take responsibility for their actions and make clear that they're not going to respect the feelings of the family members they went out of their way to hurt, then neither should be invited. They've made clear that they don't give a fuck about their "relationships" with the family, so there wouldn't be any "relationship" with them worth inviting them to the wedding over. It would be a consequence of their desire to be rude, hostile, and threatening-and they'd deserve not to be invited.

Oh please. You know full well that if this were just an example of a pattern, OP would have included it in the OP.

It's called an analogy.
It's still BS and has no logic to it at all.
