Is it wrong for me to run out on a date?
Why are you running out on her?
I'm scared that she can get infront of me, beat the shit out of me and be seriously hurt
You think your date is going to assault you? If you think that's a real possibility, you probably shouldn't be dating this woman.
I'm seriously scared of her.
Don't be afraid for no reason. I can understand if she's given you reason to fear for your safety, but if not, at least give it a shot.
