Hey, so I happily moved in a new flat with my boyfriend 2 weeks ago. In two weeks, there is an important public event for my boyfriend and his friends that we all planned to attend. This event is close to our new place, so we decided to invite everyone beforehand for a few drinks and snacks. This weekend, one of the invited friend, let's call her A, asked my boyfriend whether her friend B and her husband could also join at our place, as they will also attend the same public event. The thing is my boyfriend has met B before but is not close to her and I have never met her. I feel uncomfortable to invite someone that I don't know for the very first event in our new place, so when my boyfriend asked for my opinion, I said I would rather not invite her and he agreed. But then A insisted that we should invite B. Apparently she didn't expect us to say no and even told us that she already told B that she would be invited. So now she is threatening to not come at all and keeps pushing for us to invite B. So am I the asshole for refusing to invite B ?
