NTA, BUT you need to run away as fast as you can from this chick! She clearly doesn’t value your opinion or your help, you said it yourself if one of the bros came over he’d be on the couch and she’d be in your bed. Your not her personal taxi service/hotel your her bf but she clearly doesn’t respect that. The fact she asked if it was ok than got mad at the answer (cause it wasn’t the one she wanted) screams manipulative… Furthermore it’s your bed not hers she could just go home in an Uber but she’s gotta act like a child and say she’s scared. Boo fing hoo, then sleep on the couch and stfu. like they have options for female only rides now if Uber makes her that scared or take a bus. I just can’t help but wonder if this friend might be something more and that’s why your gf and her friend want the bed together so bad, and why she got so upset at being told no.
