A week ago my friend messaged me asking if I would like to go out for my birthday and asked when I was free, I said “I would love too, I’m free the day after my birthday”, she suggested a place to go which is quite far, she doesn’t drive so I will be driving and unable to drink.
Tonight she messages me and asks me if I can book a table and to book it for 10 people, I assumed it was just me and her as we don’t really share any other friends (maybe one friend), so she has invited 8 of her friends to what I thought was my birthday dinner. Chances are she expects me drive most of them (I have a 7 seater) there and back. I stupidly agreed to book a table so I can’t really back out and I have booked a baby sitter. My friends birthday is ten days before mine so I’m guessing this is her party and not mine and I’m just the taxi.
She has a habit of doing things like this 
So is she being a CF?, stupid question really, and I’m letting her get away with it?
Should I just book the table and invite who I would like to be there? Drive my friends there and tell her to make her own way there?
Feeling really let down, I don’t have many friends so I was excited about being asked out for my birthday. I even bought my friend a concert ticket for her birthday to see one of our favourite bands.
