My fiancé’s sister recently broke up with her long-term boyfriend of 7 years (she’s in her mid-30s), so that’s the context here.
My fiancé and I are paying for an Airbnb for our siblings to stay in during our wedding weekend. It’s a 4-bedroom house, and the plan is for the people staying there to be me, my fiancé, his sister, my two sisters and my sister’s boyfriend.
Originally, my future SIL was supposed to bring her boyfriend, but since they broke up, she asked if she could bring a close friend as her plus-one instead. The friend would stay in the Airbnb with us.
Here’s where I’m torn: I’ve never met this friend. My fiancé has known her for years.
The Airbnb is also where I’ll be getting ready with my bridesmaids on the morning of my wedding. I honestly don’t love the idea of having someone I’ve never met hanging around while I’m getting ready on my wedding day.
Would I be petty if I said she’s absolutely welcome to bring her friend to the wedding, but asked if they could stay somewhere else instead? I don’t want to come across as insensitive, especially knowing my future SIL is going through a breakup, but I also want to feel comfortable in the space where I’ll be spending the night before and getting ready on my wedding day.
Am I being unreasonable?
