i am not a good girlfriend

ok so I was hanging with this girl in a group setting. we weren't exactly that close. we just went out together a few times. I was trying to become close with her. so we go out, apparently she drank too much at the club. we went to waffle House and she threw up all over the table. the throw up started coming towards me so I moved out the way. I know I probably should have helped out more but I was really grosses our. I didn't even know what to do. the dude in our group started taking care of her. I felt bad. I don't know how I am going to make female friends when I am so horrible. but I was really grosses out. there was so much throw up .....
