Christians, am I wrong for this? Am I doing right?

People say when you date you should never bring up religion until the third time you see the guy. I don't believe in dating but if I'm going to have a partner and I'm interested and want to see if he is good, I'd be sure to talk about God who is Jesus Christ. I'd be sure he has God in life and test him before anything. I'll enlighten him about the bible and ask him question, to see whether he ever picked up the bible. If he only repeats onyl what ppl have said then there a fake trying to gety on my pants... If he flees, then eh was no good, correct? or not looking for commitment like he said?..
