So my dp and I were told about this really fun event by a friend of ours. We aren't super close but have been out together a few times, etc. I assumed she was bringing her dp to make a double date so I offered to book the tickets. Turns out she was planning on attending by herself with us, and I didn't find out until the moment I was booking. Event is a few hours away drive.
I dont mind being at the event with her as she is lovely and we do get on well, but no she has booked a night in the exact same hotel my DP and I are staying at. I was planning on doing things with him the day after, just us. We don't have a lot of money so this was sort of our Valentine's/anniversary event and we wanted to take full advantage of being away.
Would I BU to offer to drive her with us to the event but then ask that she takes the train home as we have plans the next day? Or is this mean? I don't want to make this shit for her as the whole thing was her idea, but when I agreed I had something totally different in mind.
