We didn't know he was dating anyone, and this week decides he gonna marry this girl after a year of talking to her, and she's on board. I'm so happy for him! Then he asked to bring his plus one to the preplanned vacation out of state and have her stay at our house for a few days around Christmas so she can meet the family. Keep in mind we got small kids and I never met this person before. None of us have. He's also never dated anyone seriously before, so we don't know what the type of girl she is like.

I feel weird and anxious saying yes, but I feel unsupportive for saying no. Just wondering what you would do or say?
