I took my Jewish Girlfriend to the gas station today. Apparently the gas is only for the cars.
I'm not sure I understand what you're saying, are you trying to make a joke?
Yes, she cheated on me and I wanted to make her feel bad for that and being Jewish.
Joking about the horrors that Jewish people experienced during the holocaust is wrong. No matter what issues you have with your girlfriend, you need to be sensitive to her religious background and what the history of Jewish people is and what has happened to them. You should watch a movie about the holocaust so that you can understand what they went through.
