Burner account- My fiance is an avid golfer, so for his birthday this year I am renting out golf simulators (think top golf but inside) for his closest friends (who he golfs with regularly) and some family members. Each bay allows 6 people. I have rented two. If I were to rent 3 bays we would all be fairly spread out. I invited his closest friends (all couples) and his BIL and sister. For context, I will be providing the cost of the bays, food, and dessert for all guests. Since it’s a small party I invited the people who are closest to my fiancé.

I sent a text to his cousins, inviting them and their spouses. One said "Can I invite “name”(28M) or do you want to send him the invite?" I did say to send it to him but he was not on the original list of people to invite.

I think it's important to mention the relationship between my fiance and the uninvited cousin. I don't think they have ever had an issue, however my fiance has said to me multiple times that his cousin makes him uncomfortable.

Regardless, the invite was passed to him. I don't even know if he is coming and I don’t think adding another person will be an issue. But AITA for not inviting the single cousin? I don't have a close family and would never exclude someone "just because" but I also feel like inviting someone because I invited their cousins, isn't a valid excuse either.
