Firstly it is absolutely inappropriate to discuss other dates on your date. Especially in the beginning and not when you are close to engagement.
Having said that, you are obviously getting “bad” vibes from this guy. You are not supposed to be his therapist, nor set up with him because you would be good for him. YOU are supposed to be good for each other. So if you are both not coming home with a good feeling about each other and the date, then it is not a good idea to continue.
