Dear Prudence,
My sister is dating a single father with three small children. I rent a beach house every August with two of my friends and my 22-year-old daughter. My daughter had an amazing job offer and can’t make the trip now. So there was a free bedroom.
I offered it to my sister and her boyfriend thinking they could use a couples’ vacation since I knew money was tight. Only now the boyfriend wants to bring all three kids and even went so far as to tell them they were coming without running it by me. I told them that wasn’t kosher and the kids couldn’t come. Now, my sister is beyond pissed at me. I am “ruining her relationship” and the kids are upset and disappointed. I told her she needed to point fingers at her boyfriend here. This was an adults-only vacation. You can’t randomly assume that the kids were welcome to come. We are still fighting about this. Should I just go ahead and give the bedroom to someone else?
