Hello there, I apologize if this has already been discussed, bear with me as I am new to this portion of the site. I do have two etiquette questions that are troubling:
1) On the inviting coworkers front: I work with 96 people, on a daily basis, in very close quarters. I know most of them very well, some better than I know my own family.

To avoid hurt feelings,
I had thought I might put a 'sign-up sheet' on the break room wall stating how many people they would bring etc... one guy already did this for his wedding and it seemed to go well. Another girl did not do this for hers and it caused a lot of undue drama about who wasn't invited. Even though it seems crass, I do not want to make my workplace more stressful than it already is. Sign-up sheet, or no?
2) I am very close with two of my ex's sisters and their husbands, one more so than the other. I was planning on inviting both sisters and husbands, but my fiancee says no, he doesn't want them there at all because he wants to make sure this is my day, not theirs. (They tend to be drama queens.) The sisters are starting to ask questions about my impending wedding and I'm lying about it, so far; again, to avoid hurt feelings. His heart's in the right place, but is it too harsh? How do I handle this?
Thanks so much for any help, it'd be greatly appreciated!
sorry i deleted it. sorry if i was rude.
