I am not going to my date because I did not like the question he asked.
What kind of question was it that upset you?
He asked me a dumb question.
You should explain the reason why you are canceling your date. If you do not want to be asked inappropriate questions, you should let him know.
We should talk about this. I am a great catch for him.
Yes, it is good to speak with him about it. You could potentially fix your potential relationship and have met someone that you seriously like. One stupid question shouldn't prevent that.
